matrix (applied after demosaic).<wbr/></p>
<p>The 4-channel white-balance gains are defined as:</p>
<pre><code><a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> = [ R G_<wbr/>even G_<wbr/>odd B ]
</code></pre>
<p>where <code>G_<wbr/>even</code> is the gain for green pixels on even rows of the
output,<wbr/> and <code>G_<wbr/>odd</code> is the gain for green pixels on the odd rows.<wbr/>
These may be identical for a given camera device implementation; if
the camera device does not support a separate gain for even/<wbr/>odd green
channels,<wbr/> it will use the <code>G_<wbr/>even</code> value,<wbr/> and write <code>G_<wbr/>odd</code> equal to
<code>G_<wbr/>even</code> in the output result metadata.<wbr/></p>
<p>The matrices for color transforms are defined as a 9-entry vector:</p>
<pre><code><a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ]

Similarly,<wbr/> AE precapture trigger CANCEL has no effect when AE is already locked.<wbr/></p>
<p>When an AE precapture sequence is triggered,<wbr/> AE unlock will not be able to unlock
the AE if AE is locked by the camera device internally during precapture metering
sequence In other words,<wbr/> submitting requests with AE unlock has no effect for an
ongoing precapture metering sequence.<wbr/> Otherwise,<wbr/> the precapture metering sequence
will never succeed in a sequence of preview requests where AE lock is always set
to <code>false</code>.<wbr/></p>
<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
get locked do not necessarily correspond to the settings that were present in the
latest capture result received from the camera device,<wbr/> since additional captures
and AE updates may have occurred even before the result was sent out.<wbr/> If an
application is switching between automatic and manual control and wishes to eliminate
any flicker during the switch,<wbr/> the following procedure is recommended:</p>
<ol>
<li>Starting in auto-AE mode:</li>
<li>Lock AE</li>
<li>Wait for the first result to be output that has the AE locked</li>
<li>Copy exposure settings from that result into a request,<wbr/> set the request to manual AE</li>
<li>Submit the capture request,<wbr/> proceed to run manual AE as desired.<wbr/></li>

<p>This entry is normally set to IDLE,<wbr/> or is not
included at all in the request settings.<wbr/> When included and
set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
precapture metering sequence.<wbr/></p>
<p>When set to CANCEL,<wbr/> the camera device will cancel any active
precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
If a precapture metering sequence is already completed,<wbr/> and the camera
device has implicitly locked the AE for subsequent still capture,<wbr/> the
CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
<p>The precapture sequence should be triggered before starting a
high-quality still capture for final metering decisions to
be made,<wbr/> and for firing pre-capture flash pulses to estimate
scene brightness and required final capture flash power,<wbr/> when
the flash is enabled.<wbr/></p>
<p>Normally,<wbr/> this entry should be set to START for only a
single request,<wbr/> and the application should wait until the
sequence completes before starting a new one.<wbr/></p>
<p>When a precapture metering sequence is finished,<wbr/> the camera device
may lock the auto-exposure routine internally to be able to accurately expose the
subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
internally locked AE if the application doesn't submit a still capture request after
the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
be used in devices that have earlier API levels.<wbr/></p>
<p>The exact effect of auto-exposure (AE) precapture trigger
depends on the current AE mode and state; see
<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
details.<wbr/></p>
<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
capturing a high-resolution JPEG image will automatically trigger a
precapture sequence before the high-resolution capture,<wbr/> including
potentially firing a pre-capture flash.<wbr/></p>
<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
example.<wbr/></p>
<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
the camera device will complete them in the optimal order for that device.<wbr/></p>

and will not change color balance settings until the lock is set to <code>false</code> (OFF).<wbr/></p>
<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
get locked do not necessarily correspond to the settings that were present in the
latest capture result received from the camera device,<wbr/> since additional captures
and AWB updates may have occurred even before the result was sent out.<wbr/> If an
application is switching between automatic and manual control and wishes to eliminate
any flicker during the switch,<wbr/> the following procedure is recommended:</p>
<ol>
<li>Starting in auto-AWB mode:</li>
<li>Lock AWB</li>
<li>Wait for the first result to be output that has the AWB locked</li>
<li>Copy AWB settings from that result into a request,<wbr/> set the request to manual AWB</li>
<li>Submit the capture request,<wbr/> proceed to run manual AWB as desired.<wbr/></li>
</ol>
<p>Note that AWB lock is only meaningful when
<a href="#controls_android.control.awbMode">android.<wbr/>control.<wbr/>awb<wbr/>Mode</a> is in the AUTO mode; in other modes,<wbr/>
AWB is already fixed to a specific setting.<wbr/></p>

</ul>
<p>For high speed recording use case,<wbr/> the actual maximum supported frame rate may
be lower than what camera can output,<wbr/> depending on the destination Surfaces for
the image data.<wbr/> For example,<wbr/> if the destination surface is from video encoder,<wbr/>
the application need check if the video encoder is capable of supporting the
high frame rate for a given video size,<wbr/> or it will end up with lower recording
frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the preview frame
rate will be bounded by the screen refresh rate.<wbr/></p>
<p>The camera device will only support up to 2 output high speed streams
(processed non-stalling format defined in <a href="#static_android.request.maxNumOutputStreams">android.<wbr/>request.<wbr/>max<wbr/>Num<wbr/>Output<wbr/>Streams</a>)
in this mode.<wbr/> This control will be effective only if all of below conditions are true:</p>
<ul>

min(2,<wbr/> <a href="#static_android.request.maxNumOutputStreams">android.<wbr/>request.<wbr/>max<wbr/>Num<wbr/>Output<wbr/>Streams</a>[Processed (but not-stalling)]).<wbr/></li>

<span class="entry_type_enum_name">HDR</span>
<span class="entry_type_enum_optional">[optional]</span>
<span class="entry_type_enum_notes"><p>Turn on a device-specific high dynamic range (HDR) mode.<wbr/></p>
<p>In this scene mode,<wbr/> the camera device captures images
that keep a larger range of scene illumination levels
visible in the final image.<wbr/> For example,<wbr/> when taking a
picture of a object in front of a bright window,<wbr/> both
the object and the scene through the window may be
visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
HDR mode generally takes much longer to capture a single
image,<wbr/> has no user control,<wbr/> and may have other artifacts
depending on the HDR method used.<wbr/></p>
<p>Therefore,<wbr/> HDR captures operate at a much slower rate
than regular captures.<wbr/></p>
<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
using a high dynamic range capture technique.<wbr/> On LEGACY
devices,<wbr/> captures that target a JPEG-format output will
be captured with HDR,<wbr/> and the capture intent is not
relevant.<wbr/></p>
<p>The HDR capture may involve the device capturing a burst
of images internally and combining them into one,<wbr/> or it
may involve the device using specialized high dynamic
range capture hardware.<wbr/> In all cases,<wbr/> a single image is
produced in response to a capture request submitted
while in HDR mode.<wbr/></p>
<p>Since substantial post-processing is generally needed to
produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
outputs are supported for LIMITED/<wbr/>FULL device HDR
captures,<wbr/> and only JPEG outputs are supported for LEGACY
HDR captures.<wbr/> Using a RAW output for HDR capture is not
supported.<wbr/></p>
<p>Some devices may also support always-on HDR,<wbr/> which
applies HDR processing at full frame rate.<wbr/> For these
devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
produce an HDR output with no frame rate impact compared
to normal operation,<wbr/> though the quality may be lower
than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
or capture intents,<wbr/> the images captured will be as if
the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

device will choose higher sensitivity values (<a href="#controls_android.sensor.sensitivity">android.<wbr/>sensor.<wbr/>sensitivity</a>)
under low light conditions.<wbr/></p>
<p>The camera device may be tuned to expose the images in a reduced
sensitivity range to produce the best quality images.<wbr/> For example,<wbr/>
if the <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> gives range of [100,<wbr/> 1600],<wbr/>
the camera device auto-exposure routine tuning process may limit the actual
exposure sensitivity range to [100,<wbr/> 1200] to ensure that the noise level isn't
exessive in order to preserve the image quality.<wbr/> Under this situation,<wbr/> the image under
low light may be under-exposed when the sensor max exposure time (bounded by the
<a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a> when <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is one of the
ON_<wbr/>* modes) and effective max sensitivity are reached.<wbr/> This scene mode allows the
camera device auto-exposure routine to increase the sensitivity up to the max
sensitivity specified by <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> when the scene is too
dark and the max exposure time is reached.<wbr/> The captured images may be noisier
compared with the images captured in normal FACE_<wbr/>PRIORITY mode; therefore,<wbr/> it is
recommended that the application only use this scene mode when it is capable of
reducing the noise level of the captured images.<wbr/></p>

<p>Switching between different video stabilization modes may take several
frames to initialize,<wbr/> the camera device will report the current mode
in capture result metadata.<wbr/> For example,<wbr/> When "ON" mode is requested,<wbr/>
the video stabilization modes in the first several capture results may
still be "OFF",<wbr/> and it will become "ON" when the initialization is
done.<wbr/></p>
<p>In addition,<wbr/> not all recording sizes or frame rates may be supported for
stabilization by a device that reports stabilization support.<wbr/> It is guaranteed
that an output targeting a MediaRecorder or MediaCodec will be stabilized if
the recording resolution is less than or equal to 1920 x 1080 (width less than
or equal to 1920,<wbr/> height less than or equal to 1080),<wbr/> and the recording
frame rate is less than or equal to 30fps.<wbr/> At other sizes,<wbr/> the CaptureResult
<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a> field will return
OFF if the recording output is not stabilized,<wbr/> or if there are no output
Surface types that can be stabilized.<wbr/></p>
<p>If a camera device supports both this mode and OIS
(<a href="#controls_android.lens.opticalStabilizationMode">android.<wbr/>lens.<wbr/>optical<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> turning both modes on may
produce undesirable interaction,<wbr/> so it is recommended not to enable
both at the same time.<wbr/></p>

for processed non-stalling formats.<wbr/></p>
<p>For the high speed video use case,<wbr/> the application must
select the video size and fps range from this metadata to configure the recording and
preview streams and setup the recording requests.<wbr/> For example,<wbr/> if the application intends
to do high speed recording,<wbr/> it can select the maximum size reported by this metadata to
configure output streams.<wbr/> Once the size is selected,<wbr/> application can filter this metadata
by selected size and get the supported fps ranges,<wbr/> and use these fps ranges to setup the
recording requests.<wbr/> Note that for the use case of multiple output streams,<wbr/> application
must select one unique size from this metadata to use (e.<wbr/>g.,<wbr/> preview and recording streams
must have the same size).<wbr/> Otherwise,<wbr/> the high speed capture session creation will fail.<wbr/></p>
<p>The min and max fps will be multiple times of 30fps.<wbr/></p>
<p>High speed video streaming extends significant performance pressue to camera hardware,<wbr/>
to achieve efficient high speed streaming,<wbr/> the camera device may have to aggregate
multiple frames together and send to camera device for processing where the request
controls are same for all the frames in this batch.<wbr/> Max batch size indicates
the max possible number of frames the camera device will group together for this high
speed stream configuration.<wbr/> This max batch size will be used to generate a high speed
recording request list by
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession.html#createHighSpeedRequestList">CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList</a>.<wbr/>
The max batch size for each configuration will satisfy below conditions:</p>
<ul>
<li>Each max batch size will be a divisor of its corresponding fps_<wbr/>max /<wbr/> 30.<wbr/> For example,<wbr/>
if max_<wbr/>fps is 300,<wbr/> max batch size will only be 1,<wbr/> 2,<wbr/> 5,<wbr/> or 10.<wbr/></li>
<li>The camera device may choose smaller internal batch size for each configuration,<wbr/> but
the actual batch size will be a divisor of max batch size.<wbr/> For example,<wbr/> if the max batch
size is 8,<wbr/> the actual batch size used by camera device will only be 1,<wbr/> 2,<wbr/> 4,<wbr/> or 8.<wbr/></li>
<li>The max batch size in each configuration entry must be no larger than 32.<wbr/></li>
</ul>
<p>The camera device doesn't have to support batch mode to achieve high speed video recording,<wbr/>
in such case,<wbr/> batch_<wbr/>size_<wbr/>max will be reported as 1 in each configuration entry.<wbr/></p>
<p>This fps ranges in this configuration list can only be used to create requests
that are submitted to a high speed camera capture session created by
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>.<wbr/>
The fps ranges reported in this metadata must not be used to setup capture requests for
normal capture session,<wbr/> or it will cause request error.<wbr/></p>

Note that for all high speed video configurations,<wbr/> HAL must be able to support a minimum
of two streams,<wbr/> though the application might choose to configure just one stream.<wbr/></p>
<p>The HAL may support multiple sensor modes for high speed outputs,<wbr/> for example,<wbr/> 120fps
sensor mode and 120fps recording,<wbr/> 240fps sensor mode for 240fps recording.<wbr/> The application
usually starts preview first,<wbr/> then starts recording.<wbr/> To avoid sensor mode switch caused
stutter when starting recording as much as possible,<wbr/> the application may want to ensure
the same sensor mode is used for preview and recording.<wbr/> Therefore,<wbr/> The HAL must advertise
the variable fps range [30,<wbr/> fps_<wbr/>max] for each fixed fps range in this configuration list.<wbr/>
For example,<wbr/> if the HAL advertises [120,<wbr/> 120] and [240,<wbr/> 240],<wbr/> the HAL must also advertise
[30,<wbr/> 120] and [30,<wbr/> 240] for each configuration.<wbr/> In doing so,<wbr/> if the application intends to
do 120fps recording,<wbr/> it can select [30,<wbr/> 120] to start preview,<wbr/> and [120,<wbr/> 120] to start
recording.<wbr/> For these variable fps ranges,<wbr/> it's up to the HAL to decide the actual fps
values that are suitable for smooth preview streaming.<wbr/> If the HAL sees different max_<wbr/>fps
values that fall into different sensor modes in a sequence of requests,<wbr/> the HAL must
switch the sensor mode as quick as possible to minimize the mode switch caused stutter.<wbr/></p>

<p>If AE precapture is triggered (see <a href="#controls_android.control.aePrecaptureTrigger">android.<wbr/>control.<wbr/>ae<wbr/>Precapture<wbr/>Trigger</a>)
when AE is already locked,<wbr/> the camera device will not change the exposure time

Similarly,<wbr/> AE precapture trigger CANCEL has no effect when AE is already locked.<wbr/></p>
<p>When an AE precapture sequence is triggered,<wbr/> AE unlock will not be able to unlock
the AE if AE is locked by the camera device internally during precapture metering
sequence In other words,<wbr/> submitting requests with AE unlock has no effect for an
ongoing precapture metering sequence.<wbr/> Otherwise,<wbr/> the precapture metering sequence
will never succeed in a sequence of preview requests where AE lock is always set
to <code>false</code>.<wbr/></p>
<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
get locked do not necessarily correspond to the settings that were present in the
latest capture result received from the camera device,<wbr/> since additional captures
and AE updates may have occurred even before the result was sent out.<wbr/> If an
application is switching between automatic and manual control and wishes to eliminate
any flicker during the switch,<wbr/> the following procedure is recommended:</p>
<ol>
<li>Starting in auto-AE mode:</li>
<li>Lock AE</li>
<li>Wait for the first result to be output that has the AE locked</li>
<li>Copy exposure settings from that result into a request,<wbr/> set the request to manual AE</li>
<li>Submit the capture request,<wbr/> proceed to run manual AE as desired.<wbr/></li>

<p>This entry is normally set to IDLE,<wbr/> or is not
included at all in the request settings.<wbr/> When included and
set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
precapture metering sequence.<wbr/></p>
<p>When set to CANCEL,<wbr/> the camera device will cancel any active
precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
If a precapture metering sequence is already completed,<wbr/> and the camera
device has implicitly locked the AE for subsequent still capture,<wbr/> the
CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
<p>The precapture sequence should be triggered before starting a
high-quality still capture for final metering decisions to
be made,<wbr/> and for firing pre-capture flash pulses to estimate
scene brightness and required final capture flash power,<wbr/> when
the flash is enabled.<wbr/></p>
<p>Normally,<wbr/> this entry should be set to START for only a
single request,<wbr/> and the application should wait until the
sequence completes before starting a new one.<wbr/></p>
<p>When a precapture metering sequence is finished,<wbr/> the camera device
may lock the auto-exposure routine internally to be able to accurately expose the
subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
internally locked AE if the application doesn't submit a still capture request after
the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
be used in devices that have earlier API levels.<wbr/></p>
<p>The exact effect of auto-exposure (AE) precapture trigger
depends on the current AE mode and state; see
<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
details.<wbr/></p>
<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
capturing a high-resolution JPEG image will automatically trigger a
precapture sequence before the high-resolution capture,<wbr/> including
potentially firing a pre-capture flash.<wbr/></p>
<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
example.<wbr/></p>
<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
the camera device will complete them in the optimal order for that device.<wbr/></p>

request (<a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a> <code>==</code> START).<wbr/> After an AF trigger,<wbr/> the afState will end
up with either FOCUSED_<wbr/>LOCKED or NOT_<wbr/>FOCUSED_<wbr/>LOCKED state (see
<a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> which indicates that the lens is
locked and will not move.<wbr/> If camera movement (e.<wbr/>g.<wbr/> tilting camera) causes the lens to move
after the lens is locked,<wbr/> the HAL must compensate this movement appropriately such that
the same focal plane remains in focus.<wbr/></p>
<p>When afMode is one of the continuous auto focus modes,<wbr/> the HAL is free to start a AF
scan whenever it's not locked.<wbr/> When the lens is locked after an AF trigger
(see <a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> the HAL should maintain the
same lock behavior as above.<wbr/></p>
<p>When afMode is OFF,<wbr/> the application controls focus manually.<wbr/> The accuracy of the
focus distance control depends on the <a href="#static_android.lens.info.focusDistanceCalibration">android.<wbr/>lens.<wbr/>info.<wbr/>focus<wbr/>Distance<wbr/>Calibration</a>.<wbr/>
However,<wbr/> the lens must not move regardless of the camera movement for any focus distance
manual control.<wbr/></p>
<p>To put this in concrete terms,<wbr/> if the camera has lens elements which may move based on
camera orientation or motion (e.<wbr/>g.<wbr/> due to gravity),<wbr/> then the HAL must drive the lens to
remain in a fixed position invariant to the camera's orientation or motion,<wbr/> for example,<wbr/>
by using accelerometer measurements in the lens control logic.<wbr/> This is a typical issue
that will arise on camera modules with open-loop VCMs.<wbr/></p>

<li>Starting in auto-AWB mode:</li>
<li>Lock AWB</li>
<li>Wait for the first result to be output that has the AWB locked</li>

<p>For the above table,<wbr/> the camera device may skip reporting any state changes that happen

can be skipped in that manner is called a transient state.<wbr/></p>

<span class="entry_type_enum_notes"><p>Turn on a device-specific high dynamic range (HDR) mode.<wbr/></p>
<p>In this scene mode,<wbr/> the camera device captures images
that keep a larger range of scene illumination levels
visible in the final image.<wbr/> For example,<wbr/> when taking a
picture of a object in front of a bright window,<wbr/> both
the object and the scene through the window may be
visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
HDR mode generally takes much longer to capture a single
image,<wbr/> has no user control,<wbr/> and may have other artifacts
depending on the HDR method used.<wbr/></p>
<p>Therefore,<wbr/> HDR captures operate at a much slower rate
than regular captures.<wbr/></p>
<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
using a high dynamic range capture technique.<wbr/> On LEGACY
devices,<wbr/> captures that target a JPEG-format output will
be captured with HDR,<wbr/> and the capture intent is not
relevant.<wbr/></p>
<p>The HDR capture may involve the device capturing a burst
of images internally and combining them into one,<wbr/> or it
may involve the device using specialized high dynamic
range capture hardware.<wbr/> In all cases,<wbr/> a single image is
produced in response to a capture request submitted
while in HDR mode.<wbr/></p>
<p>Since substantial post-processing is generally needed to
produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
outputs are supported for LIMITED/<wbr/>FULL device HDR
captures,<wbr/> and only JPEG outputs are supported for LEGACY
HDR captures.<wbr/> Using a RAW output for HDR capture is not
supported.<wbr/></p>
<p>Some devices may also support always-on HDR,<wbr/> which
applies HDR processing at full frame rate.<wbr/> For these
devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
produce an HDR output with no frame rate impact compared
to normal operation,<wbr/> though the quality may be lower
than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
or capture intents,<wbr/> the images captured will be as if
the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

<p>The camera device may be tuned to expose the images in a reduced
sensitivity range to produce the best quality images.<wbr/> For example,<wbr/>
if the <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> gives range of [100,<wbr/> 1600],<wbr/>
the camera device auto-exposure routine tuning process may limit the actual
exposure sensitivity range to [100,<wbr/> 1200] to ensure that the noise level isn't
exessive in order to preserve the image quality.<wbr/> Under this situation,<wbr/> the image under
low light may be under-exposed when the sensor max exposure time (bounded by the
<a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a> when <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is one of the

camera device auto-exposure routine to increase the sensitivity up to the max
sensitivity specified by <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> when the scene is too
dark and the max exposure time is reached.<wbr/> The captured images may be noisier

edge enhancement applied,<wbr/> while higher-resolution streams have no edge enhancement
applied.<wbr/> The level of edge enhancement for low-resolution streams is tuned so that
frame rate is not impacted,<wbr/> and the quality is equal to or better than FAST (since it
is only applied to lower-resolution outputs,<wbr/> quality may improve from FAST).<wbr/></p>
<p>This mode is intended to be used by applications operating in a zero-shutter-lag mode
with YUV or PRIVATE reprocessing,<wbr/> where the application continuously captures
high-resolution intermediate buffers into a circular buffer,<wbr/> from which a final image is
produced via reprocessing when a user takes a picture.<wbr/> For such a use case,<wbr/> the
high-resolution buffers must not have edge enhancement applied to maximize efficiency of
preview and to avoid double-applying enhancement when reprocessed,<wbr/> while low-resolution
buffers (used for recording or preview,<wbr/> generally) need edge enhancement applied for
reasonable preview quality.<wbr/></p>
<p>This mode is guaranteed to be supported by devices that support either the
YUV_<wbr/>REPROCESSING or PRIVATE_<wbr/>REPROCESSING capabilities
(<a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a> lists either of those capabilities) and it will

not slow down capture rate when applying edge enhancement.<wbr/> FAST may be the same as OFF if

<p>ZERO_<wbr/>SHUTTER_<wbr/>LAG is meant to be used by applications that maintain a continuous circular

<p>OIS is used to compensate for motion blur due to small
movements of the camera during capture.<wbr/> Unlike digital image
stabilization (<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> OIS
makes use of mechanical elements to stabilize the camera
sensor,<wbr/> and thus allows for longer exposure times before
camera shake becomes apparent.<wbr/></p>
<p>Switching between different optical stabilization modes may take several
frames to initialize,<wbr/> the camera device will report the current mode in
capture result metadata.<wbr/> For example,<wbr/> When "ON" mode is requested,<wbr/> the
optical stabilization modes in the first several capture results may still
be "OFF",<wbr/> and it will become "ON" when the initialization is done.<wbr/></p>
<p>If a camera device supports both OIS and digital image stabilization
(<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> turning both modes on may produce undesirable
interaction,<wbr/> so it is recommended not to enable both at the same time.<wbr/></p>
<p>Not all devices will support OIS; see
<a href="#static_android.lens.info.availableOpticalStabilization">android.<wbr/>lens.<wbr/>info.<wbr/>available<wbr/>Optical<wbr/>Stabilization</a> for

based on resolution.<wbr/> Streams at maximum recording resolution (see <a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createCaptureSession">CameraDevice#createCaptureSession</a>) or below have noise
reduction applied,<wbr/> while higher-resolution streams have MINIMAL (if supported) or no
noise reduction applied (if MINIMAL is not supported.<wbr/>) The degree of noise reduction
for low-resolution streams is tuned so that frame rate is not impacted,<wbr/> and the quality
is equal to or better than FAST (since it is only applied to lower-resolution outputs,<wbr/>
quality may improve from FAST).<wbr/></p>
<p>This mode is intended to be used by applications operating in a zero-shutter-lag mode
with YUV or PRIVATE reprocessing,<wbr/> where the application continuously captures
high-resolution intermediate buffers into a circular buffer,<wbr/> from which a final image is
produced via reprocessing when a user takes a picture.<wbr/> For such a use case,<wbr/> the
high-resolution buffers must not have noise reduction applied to maximize efficiency of
preview and to avoid over-applying noise filtering when reprocessing,<wbr/> while
low-resolution buffers (used for recording or preview,<wbr/> generally) need noise reduction
applied for reasonable preview quality.<wbr/></p>
<p>This mode is guaranteed to be supported by devices that support either the
YUV_<wbr/>REPROCESSING or PRIVATE_<wbr/>REPROCESSING capabilities
(<a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a> lists either of those capabilities) and it will

<p>The noise reduction algorithm attempts to improve image quality by removing

<p>MINIMAL means that only sensor raw domain basic noise reduction is enabled ,<wbr/>to remove
demosaicing or other processing artifacts.<wbr/> For YUV_<wbr/>REPROCESSING,<wbr/> MINIMAL is same as OFF.<wbr/>

noise reduction to low-resolution streams (below maximum recording resolution) to maximize
preview quality,<wbr/> but does not apply noise reduction to high-resolution streams,<wbr/> since
those will be reprocessed later if necessary.<wbr/></p>

formats respectively.<wbr/> For example,<wbr/> assuming that JPEG is typically a processed and
stalling stream,<wbr/> if max raw sensor format output stream number is 1,<wbr/> max YUV streams
number is 3,<wbr/> and max JPEG stream number is 2,<wbr/> then this tuple should be <code>(1,<wbr/> 3,<wbr/> 2)</code>.<wbr/></p>
<p>This lists the upper bound of the number of output streams supported by
the camera device.<wbr/> Using more streams simultaneously may require more hardware and
CPU resources that will consume more power.<wbr/> The image format for an output stream can
be any supported format provided by <a href="#static_android.scaler.availableStreamConfigurations">android.<wbr/>scaler.<wbr/>available<wbr/>Stream<wbr/>Configurations</a>.<wbr/>
The formats defined in <a href="#static_android.scaler.availableStreamConfigurations">android.<wbr/>scaler.<wbr/>available<wbr/>Stream<wbr/>Configurations</a> can be catergorized
into the 3 stream types as below:</p>
<ul>

the capability of a specialized operating mode with many limitations (see below),<wbr/> which

</ul>
<p>For high speed recording use case,<wbr/> the actual maximum supported frame rate may
be lower than what camera can output,<wbr/> depending on the destination Surfaces for
the image data.<wbr/> For example,<wbr/> if the destination surface is from video encoder,<wbr/>
the application need check if the video encoder is capable of supporting the
high frame rate for a given video size,<wbr/> or it will end up with lower recording
frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the actual preview frame
rate will be bounded by the screen refresh rate.<wbr/></p>
<p>The camera device will only support up to 2 high speed simultaneous output surfaces
(preview and recording surfaces)
in this mode.<wbr/> Above controls will be effective only if all of below conditions are true:</p>
<ul>
<li>The application creates a camera capture session with no more than 2 surfaces via
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>.<wbr/> The

<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>

<p>Switching to a FPS range that has different maximum FPS may trigger some camera device
reconfigurations,<wbr/> which may introduce extra latency.<wbr/> It is recommended that
the application avoids unnecessary maximum target FPS changes as much as possible

<p>The crop region is applied after the RAW to other color
space (e.<wbr/>g.<wbr/> YUV) conversion.<wbr/> Since raw streams
(e.<wbr/>g.<wbr/> RAW16) don't have the conversion stage,<wbr/> they are not
croppable.<wbr/> The crop region will be ignored by raw streams.<wbr/></p>
<p>For non-raw streams,<wbr/> any additional per-stream cropping will
be done to maximize the final pixel area of the stream.<wbr/></p>
<p>For example,<wbr/> if the crop region is set to a 4:3 aspect
ratio,<wbr/> then 4:3 streams will use the exact crop
region.<wbr/> 16:9 streams will further crop vertically
(letterbox).<wbr/></p>
<p>Conversely,<wbr/> if the crop region is set to a 16:9,<wbr/> then 4:3
outputs will crop horizontally (pillarbox),<wbr/> and 16:9
streams will match exactly.<wbr/> These additional crops will
be centered within the crop region.<wbr/></p>
<p>The width and height of the crop region cannot
be set to be smaller than

<p>For a set of output streams configured,<wbr/> if the sensor output is cropped to a smaller

<p>The HAL need handle the cropRegion as if the sensor crop size is the effective active
array size.<wbr/>More specifically,<wbr/> the HAL must transform the request cropRegion from
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a> to the sensor cropped pixel area size in this way:</p>
<ol>
<li>Translate the requested cropRegion w.<wbr/>r.<wbr/>t.,<wbr/> the left top corner of the sensor
cropped pixel area by (tx,<wbr/> ty),<wbr/>
where <code>tx = sensorCrop.<wbr/>top * (sensorCrop.<wbr/>height /<wbr/> activeArraySize.<wbr/>height)</code>
and <code>tx = sensorCrop.<wbr/>left * (sensorCrop.<wbr/>width /<wbr/> activeArraySize.<wbr/>width)</code>.<wbr/> The
(sensorCrop.<wbr/>top,<wbr/> sensorCrop.<wbr/>left) is the coordinate based off the
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/></li>
<li>Scale the width and height of requested cropRegion with scaling factor of
sensor<wbr/>Crop.<wbr/>width/<wbr/>active<wbr/>Array<wbr/>Size.<wbr/>width and sensor<wbr/>Crop.<wbr/>height/<wbr/>active<wbr/>Array<wbr/>Size.<wbr/>height
respectively.<wbr/>
Once this new cropRegion is calculated,<wbr/> the HAL must use this region to crop the image
with regard to the sensor crop size (effective active array size).<wbr/> The HAL still need
follow the general cropping rule for this new cropRegion and effective active
array size.<wbr/></li>
</ol>
</li>
<li>
<p>The HAL must report the cropRegion with regard to <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/>
The HAL need convert the new cropRegion generated above w.<wbr/>r.<wbr/>t.,<wbr/> full active array size.<wbr/>
The reported cropRegion may be slightly different with the requested cropRegion since
the HAL may adjust the crop region to account for rounding,<wbr/> conversion error,<wbr/> or other

as referred in public API) is a format for raw image buffers
coming from an image sensor.<wbr/></p>
<p>The actual structure of buffers of this format is
platform-specific,<wbr/> but must follow several constraints:</p>
<ol>
<li>No image post-processing operations may have been applied to
buffers of this type.<wbr/> These buffers contain raw image data coming
directly from the image sensor.<wbr/></li>
<li>If a buffer of this format is passed to the camera device for
reprocessing,<wbr/> the resulting images will be identical to the images
produced if the buffer had come directly from the sensor and was
processed with the same settings.<wbr/></li>
</ol>
<p>The intended use for this format is to allow access to the native
raw format buffers coming directly from the camera sensor without
any additional conversions or decrease in framerate.<wbr/></p>

<p>A stall duration is how much extra time would get added
to the normal minimum frame duration for a repeating request
that has streams with non-zero stall.<wbr/></p>
<p>For example,<wbr/> consider JPEG captures which have the following
characteristics:</p>
<ul>
<li>JPEG streams act like processed YUV streams in requests for which
they are not included; in requests in which they are directly
referenced,<wbr/> they act as JPEG streams.<wbr/> This is because supporting a
JPEG stream requires the underlying YUV data to always be ready for
use by a JPEG encoder,<wbr/> but the encoder will only be used (and impact
frame duration) on requests that actually reference a JPEG stream.<wbr/></li>
<li>The JPEG processor can run concurrently to the rest of the camera
pipeline,<wbr/> but cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>In other words,<wbr/> using a repeating YUV request would result
in a steady frame rate (let's say it's 30 FPS).<wbr/> If a single
JPEG request is submitted periodically,<wbr/> the frame rate will stay
at 30 FPS (as long as we wait for the previous JPEG to return each
time).<wbr/> If we try to submit a repeating YUV + JPEG request,<wbr/> then
the frame rate will drop from 30 FPS.<wbr/></p>
<p>In general,<wbr/> submitting a new request with a non-0 stall time
stream will <em>not</em> cause a frame rate drop unless there are still
outstanding buffers for that stream from previous requests.<wbr/></p>
<p>Submitting a repeating request with streams (call this <code>S</code>)
is the same as setting the minimum frame duration from
the normal minimum frame duration corresponding to <code>S</code>,<wbr/> added with
the maximum stall duration for <code>S</code>.<wbr/></p>
<p>If interleaving requests with and without a stall duration,<wbr/>
a request will stall by the maximum of the remaining times
for each can-stall stream with outstanding buffers.<wbr/></p>
<p>This means that a stalling request will not have an exposure start
until the stall has completed.<wbr/></p>
<p>This should correspond to the stall duration when only that stream is
active,<wbr/> with all processing (typically in android.<wbr/>*.<wbr/>mode) set to FAST
or OFF.<wbr/> Setting any of the processing modes to HIGH_<wbr/>QUALITY
effectively results in an indeterminate stall duration for all
streams in a request (the regular stall calculation rules are
ignored).<wbr/></p>
<p>The following formats may always have a stall duration:</p>
<ul>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#JPEG">ImageFormat#JPEG</a></li>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#RAW_SENSOR">ImageFormat#RAW_<wbr/>SENSOR</a></li>
</ul>
<p>The following formats will never have a stall duration:</p>
<ul>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#YUV_420_888">Image<wbr/>Format#YUV_<wbr/>420_<wbr/>888</a></li>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#RAW10">ImageFormat#RAW10</a></li>
</ul>
<p>All other formats may or may not have an allowed stall duration on
a per-capability basis; refer to <a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a>
for more details.<wbr/></p>

<p>Output streams use this rectangle to produce their output,<wbr/>
cropping to a smaller region if necessary to maintain the
stream's aspect ratio,<wbr/> then scaling the sensor input to
match the output's configured resolution.<wbr/></p>
<p>The crop region is applied after the RAW to other color
space (e.<wbr/>g.<wbr/> YUV) conversion.<wbr/> Since raw streams
(e.<wbr/>g.<wbr/> RAW16) don't have the conversion stage,<wbr/> they are not
croppable.<wbr/> The crop region will be ignored by raw streams.<wbr/></p>
<p>For non-raw streams,<wbr/> any additional per-stream cropping will
be done to maximize the final pixel area of the stream.<wbr/></p>
<p>For example,<wbr/> if the crop region is set to a 4:3 aspect
ratio,<wbr/> then 4:3 streams will use the exact crop
region.<wbr/> 16:9 streams will further crop vertically
(letterbox).<wbr/></p>
<p>Conversely,<wbr/> if the crop region is set to a 16:9,<wbr/> then 4:3
outputs will crop horizontally (pillarbox),<wbr/> and 16:9
streams will match exactly.<wbr/> These additional crops will
be centered within the crop region.<wbr/></p>
<p>The width and height of the crop region cannot
be set to be smaller than

<p>The HAL need handle the cropRegion as if the sensor crop size is the effective active

<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a> to the sensor cropped pixel area size in this way:</p>

cropped pixel area by (tx,<wbr/> ty),<wbr/>
where <code>tx = sensorCrop.<wbr/>top * (sensorCrop.<wbr/>height /<wbr/> activeArraySize.<wbr/>height)</code>

<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/></li>
<li>Scale the width and height of requested cropRegion with scaling factor of
sensor<wbr/>Crop.<wbr/>width/<wbr/>active<wbr/>Array<wbr/>Size.<wbr/>width and sensor<wbr/>Crop.<wbr/>height/<wbr/>active<wbr/>Array<wbr/>Size.<wbr/>height
respectively.<wbr/>
Once this new cropRegion is calculated,<wbr/> the HAL must use this region to crop the image
with regard to the sensor crop size (effective active array size).<wbr/> The HAL still need
follow the general cropping rule for this new cropRegion and effective active
array size.<wbr/></li>
</ol>
</li>
<li>
<p>The HAL must report the cropRegion with regard to <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/>
The HAL need convert the new cropRegion generated above w.<wbr/>r.<wbr/>t.,<wbr/> full active array size.<wbr/>
The reported cropRegion may be slightly different with the requested cropRegion since
the HAL may adjust the crop region to account for rounding,<wbr/> conversion error,<wbr/> or other

<p>The maximum frame rate that can be supported by a camera subsystem is
a function of many factors:</p>
<ul>
<li>Requested resolutions of output image streams</li>
<li>Availability of binning /<wbr/> skipping modes on the imager</li>
<li>The bandwidth of the imager interface</li>
<li>The bandwidth of the various ISP processing blocks</li>
</ul>
<p>Since these factors can vary greatly between different ISPs and
sensors,<wbr/> the camera abstraction tries to represent the bandwidth
restrictions with as simple a model as possible.<wbr/></p>
<p>The model presented has the following characteristics:</p>
<ul>
<li>The image sensor is always configured to output the smallest
resolution possible given the application's requested output stream
sizes.<wbr/> The smallest resolution is defined as being at least as large
as the largest requested output stream size; the camera pipeline must
never digitally upsample sensor data when the crop region covers the
whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
resolutions are configured,<wbr/> the sensor can provide a higher frame
rate.<wbr/></li>
<li>Since any request may use any or all the currently configured
output streams,<wbr/> the sensor and ISP must be configured to support
scaling a single capture to all the streams at the same time.<wbr/> This
means the camera pipeline must be ready to produce the largest
requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
frame rate of a given configured stream set is governed only by the
largest requested stream resolution.<wbr/></li>
<li>Using more than one output stream in a request does not affect the
frame duration.<wbr/></li>
<li>Certain format-streams may need to do additional background processing
before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
can run concurrently to the rest of the camera pipeline,<wbr/> but
cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
These are used to determine the maximum frame rate /<wbr/> minimum frame
duration that is possible for a given stream configuration.<wbr/></p>
<p>Specifically,<wbr/> the application can use the following rules to
determine the minimum frame duration it can request from the camera
device:</p>
<ol>
<li>Let the set of currently configured input/<wbr/>output streams
be called <code>S</code>.<wbr/></li>
<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
called <code>F</code>.<wbr/></li>
<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
</ol>
<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
determines the steady state frame rate that the application will get
if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
request be called <code>Rsimple</code>.<wbr/></p>
<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
by a single capture of a new request <code>Rstall</code> (which has at least
one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
same minimum frame duration this will not cause a frame rate loss
if all buffers from the previous <code>Rstall</code> have already been
delivered.<wbr/></p>

has been applied,<wbr/> and should be treated as the active region rectangle for any of the
raw formats.<wbr/> All metadata associated with raw processing (e.<wbr/>g.<wbr/> the lens shading
correction map,<wbr/> and radial distortion fields) treats the top,<wbr/> left of this rectangle as
the origin,<wbr/> (0,<wbr/>0).<wbr/></p>
<p>The size of this region determines the maximum field of view and the maximum number of
pixels that an image from this sensor can contain,<wbr/> prior to the application of
geometric distortion correction.<wbr/> The effective maximum pixel dimensions of a
post-distortion-corrected image is given by the <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>
field,<wbr/> and the effective maximum field of view for a post-distortion-corrected image
can be calculated by applying the geometric distortion correction fields to this
rectangle,<wbr/> and cropping to the rectangle given in <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/></p>
<p>E.<wbr/>g.<wbr/> to calculate position of a pixel,<wbr/> (x,<wbr/>y),<wbr/> in a processed YUV output image with the
dimensions in <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a> given the position of a pixel,<wbr/>
(x',<wbr/> y'),<wbr/> in the raw pixel array with dimensions give in
<a href="#static_android.sensor.info.pixelArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pixel<wbr/>Array<wbr/>Size</a>:</p>
<ol>
<li>Choose a pixel (x',<wbr/> y') within the active array region of the raw buffer given in
<a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a>,<wbr/> otherwise this pixel is considered
to be outside of the FOV,<wbr/> and will not be shown in the processed output image.<wbr/></li>
<li>Apply geometric distortion correction to get the post-distortion pixel coordinate,<wbr/>
(x_<wbr/>i,<wbr/> y_<wbr/>i).<wbr/> When applying geometric correction metadata,<wbr/> note that metadata for raw
buffers is defined relative to the top,<wbr/> left of the
<a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a> rectangle.<wbr/></li>
<li>If the resulting corrected pixel coordinate is within the region given in
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>,<wbr/> then the position of this pixel in the
processed output image buffer is <code>(x_<wbr/>i - activeArray.<wbr/>left,<wbr/> y_<wbr/>i - activeArray.<wbr/>top)</code>,<wbr/>
when the top,<wbr/> left coordinate of that buffer is treated as (0,<wbr/> 0).<wbr/></li>
</ol>
<p>Thus,<wbr/> for pixel x',<wbr/>y' = (25,<wbr/> 25) on a sensor where <a href="#static_android.sensor.info.pixelArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pixel<wbr/>Array<wbr/>Size</a>
is (100,<wbr/>100),<wbr/> <a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a> is (10,<wbr/> 10,<wbr/> 100,<wbr/> 100),<wbr/>
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a> is (20,<wbr/> 20,<wbr/> 80,<wbr/> 80),<wbr/> and the geometric distortion
correction doesn't change the pixel coordinate,<wbr/> the resulting pixel selected in
pixel coordinates would be x,<wbr/>y = (25,<wbr/> 25) relative to the top,<wbr/>left of the raw buffer
with dimensions given in <a href="#static_android.sensor.info.pixelArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pixel<wbr/>Array<wbr/>Size</a>,<wbr/> and would be (5,<wbr/> 5)
relative to the top,<wbr/>left of post-processed YUV output buffer with dimensions given in
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/></p>
<p>The currently supported fields that correct for geometric distortion are:</p>
<ol>
<li><a href="#static_android.lens.radialDistortion">android.<wbr/>lens.<wbr/>radial<wbr/>Distortion</a>.<wbr/></li>
</ol>
<p>If all of the geometric distortion fields are no-ops,<wbr/> this rectangle will be the same
as the post-distortion-corrected rectangle given in
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/></p>
<p>This rectangle is defined relative to the full pixel array; (0,<wbr/>0) is the top-left of
the full pixel array,<wbr/> and the size of the full pixel array is given by
<a href="#static_android.sensor.info.pixelArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pixel<wbr/>Array<wbr/>Size</a>.<wbr/></p>
<p>The pre-correction active array may be smaller than the full pixel array,<wbr/> since the
full array may include black calibration pixels or other inactive regions.<wbr/></p>

<p>The maximum frame rate that can be supported by a camera subsystem is
a function of many factors:</p>
<ul>
<li>Requested resolutions of output image streams</li>
<li>Availability of binning /<wbr/> skipping modes on the imager</li>
<li>The bandwidth of the imager interface</li>
<li>The bandwidth of the various ISP processing blocks</li>
</ul>
<p>Since these factors can vary greatly between different ISPs and
sensors,<wbr/> the camera abstraction tries to represent the bandwidth
restrictions with as simple a model as possible.<wbr/></p>
<p>The model presented has the following characteristics:</p>
<ul>
<li>The image sensor is always configured to output the smallest
resolution possible given the application's requested output stream
sizes.<wbr/> The smallest resolution is defined as being at least as large
as the largest requested output stream size; the camera pipeline must
never digitally upsample sensor data when the crop region covers the
whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
resolutions are configured,<wbr/> the sensor can provide a higher frame
rate.<wbr/></li>
<li>Since any request may use any or all the currently configured
output streams,<wbr/> the sensor and ISP must be configured to support
scaling a single capture to all the streams at the same time.<wbr/> This
means the camera pipeline must be ready to produce the largest
requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
frame rate of a given configured stream set is governed only by the
largest requested stream resolution.<wbr/></li>
<li>Using more than one output stream in a request does not affect the
frame duration.<wbr/></li>
<li>Certain format-streams may need to do additional background processing
before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
can run concurrently to the rest of the camera pipeline,<wbr/> but
cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
These are used to determine the maximum frame rate /<wbr/> minimum frame
duration that is possible for a given stream configuration.<wbr/></p>
<p>Specifically,<wbr/> the application can use the following rules to
determine the minimum frame duration it can request from the camera
device:</p>
<ol>
<li>Let the set of currently configured input/<wbr/>output streams
be called <code>S</code>.<wbr/></li>
<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
called <code>F</code>.<wbr/></li>
<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
</ol>
<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
determines the steady state frame rate that the application will get
if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
request be called <code>Rsimple</code>.<wbr/></p>
<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
by a single capture of a new request <code>Rstall</code> (which has at least
one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
same minimum frame duration this will not cause a frame rate loss
if all buffers from the previous <code>Rstall</code> have already been
delivered.<wbr/></p>

<p>This value is an estimate of the worst case split between the

filter array.<wbr/></p>
<p>The green split is calculated as follows:</p>
<ol>
<li>A 5x5 pixel (or larger) window W within the active sensor array is
chosen.<wbr/> The term 'pixel' here is taken to mean a group of 4 Bayer
mosaic channels (R,<wbr/> Gr,<wbr/> Gb,<wbr/> B).<wbr/> The location and size of the window
chosen is implementation defined,<wbr/> and should be chosen to provide a
green split estimate that is both representative of the entire image
for this camera sensor,<wbr/> and can be calculated quickly.<wbr/></li>
<li>The arithmetic mean of the green channels from the red
rows (mean_<wbr/>Gr) within W is computed.<wbr/></li>
<li>The arithmetic mean of the green channels from the blue
rows (mean_<wbr/>Gb) within W is computed.<wbr/></li>
<li>The maximum ratio R of the two means is computed as follows:
<code>R = max((mean_<wbr/>Gr + 1)/<wbr/>(mean_<wbr/>Gb + 1),<wbr/> (mean_<wbr/>Gb + 1)/<wbr/>(mean_<wbr/>Gr + 1))</code></li>
</ol>
<p>The ratio R is the green split divergence reported for this property,<wbr/>
which represents how much the green channels differ in the mosaic
pattern.<wbr/> This value is typically used to determine the treatment of
the green mosaic channels when demosaicing.<wbr/></p>
<p>The green split value can be roughly interpreted as follows:</p>
<ul>
<li>R &lt; 1.<wbr/>03 is a negligible split (&lt;3% divergence).<wbr/></li>
<li>1.<wbr/>20 &lt;= R &gt;= 1.<wbr/>03 will require some software
correction to avoid demosaic errors (3-20% divergence).<wbr/></li>

<p>The tonemapCurve consist of three curves for each of red,<wbr/> green,<wbr/> and blue
channels respectively.<wbr/> The following example uses the red channel as an
example.<wbr/> The same logic applies to green and blue channel.<wbr/>
Each channel's curve is defined by an array of control points:</p>
<pre><code>curveRed =
[ P0(in,<wbr/> out),<wbr/> P1(in,<wbr/> out),<wbr/> P2(in,<wbr/> out),<wbr/> P3(in,<wbr/> out),<wbr/> ...,<wbr/> PN(in,<wbr/> out) ]
2 &lt;= N &lt;= <a href="#static_android.tonemap.maxCurvePoints">android.<wbr/>tonemap.<wbr/>max<wbr/>Curve<wbr/>Points</a></code></pre>
<p>These are sorted in order of increasing <code>Pin</code>; it is always
guaranteed that input values 0.<wbr/>0 and 1.<wbr/>0 are included in the list to
define a complete mapping.<wbr/> For input values between control points,<wbr/>
the camera device must linearly interpolate between the control
points.<wbr/></p>
<p>Each curve can have an independent number of points,<wbr/> and the number
of points can be less than max (that is,<wbr/> the request doesn't have to
always provide a curve with number of points equivalent to
<a href="#static_android.tonemap.maxCurvePoints">android.<wbr/>tonemap.<wbr/>max<wbr/>Curve<wbr/>Points</a>).<wbr/></p>
<p>A few examples,<wbr/> and their corresponding graphical mappings; these
only specify the red channel and the precision is limited to 4

<p>When set to <code>true</code> (ON),<wbr/> the values used for black-level
compensation will not change until the lock is set to

<p>Since changes to certain capture parameters (such as
exposure time) may require resetting of black level
compensation,<wbr/> the camera device must report whether setting
the black level lock was successful in the output result
metadata.<wbr/></p>
<p>For example,<wbr/> if a sequence of requests is as follows:</p>
<ul>
<li>Request 1: Exposure = 10ms,<wbr/> Black level lock = OFF</li>
<li>Request 2: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Request 3: Exposure = 10ms,<wbr/> Black level lock = ON</li>

<li>Request 5: Exposure = 20ms,<wbr/> Black level lock = ON</li>
<li>Request 6: Exposure = 20ms,<wbr/> Black level lock = ON</li>
</ul>
<p>And the exposure change in Request 4 requires the camera
device to reset the black level offsets,<wbr/> then the output
result metadata is expected to be:</p>
<ul>
<li>Result 1: Exposure = 10ms,<wbr/> Black level lock = OFF</li>
<li>Result 2: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Result 3: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Result 4: Exposure = 20ms,<wbr/> Black level lock = OFF</li>
<li>Result 5: Exposure = 20ms,<wbr/> Black level lock = ON</li>
<li>Result 6: Exposure = 20ms,<wbr/> Black level lock = ON</li>
</ul>
<p>This indicates to the application that on frame 4,<wbr/> black
levels were reset due to exposure value changes,<wbr/> and pixel
values may not be consistent across captures.<wbr/></p>
<p>The camera device will maintain the lock to the extent
possible,<wbr/> only overriding the lock to OFF when changes to
other request parameters require a black level recalculation

<p>When a request is submitted to the camera device,<wbr/> there is usually a
delay of several frames before the controls get applied.<wbr/> A camera
device may either choose to account for this delay by implementing a
pipeline and carefully submit well-timed atomic control updates,<wbr/> or
it may start streaming control changes that span over several frame
boundaries.<wbr/></p>
<p>In the latter case,<wbr/> whenever a request's settings change relative to
the previous submitted request,<wbr/> the full set of changes may take
multiple frame durations to fully take effect.<wbr/> Some settings may
take effect sooner (in less frame durations) than others.<wbr/></p>
<p>While a set of control changes are being propagated,<wbr/> this value
will be CONVERGING.<wbr/></p>
<p>Once it is fully known that a set of control changes have been
finished propagating,<wbr/> and the resulting updated control settings
have been read back by the camera device,<wbr/> this value will be set
to a non-negative frame number (corresponding to the request to
which the results have synchronized to).<wbr/></p>
<p>Older camera device implementations may not have a way to detect
when all camera controls have been applied,<wbr/> and will always set this
value to UNKNOWN.<wbr/></p>
<p>FULL capability devices will always have this value set to the
frame number of the request corresponding to this result.<wbr/></p>
<p><em>Further details</em>:</p>
<ul>
<li>Whenever a request differs from the last request,<wbr/> any future
results not yet returned may have this value set to CONVERGING (this
could include any in-progress captures not yet returned by the camera
device,<wbr/> for more details see pipeline considerations below).<wbr/></li>
<li>Submitting a series of multiple requests that differ from the
previous request (e.<wbr/>g.<wbr/> r1,<wbr/> r2,<wbr/> r3 s.<wbr/>t.<wbr/> r1 != r2 != r3)
moves the new synchronization frame to the last non-repeating
request (using the smallest frame number from the contiguous list of
repeating requests).<wbr/></li>
<li>Submitting the same request repeatedly will not change this value
to CONVERGING,<wbr/> if it was already a non-negative value.<wbr/></li>
<li>When this value changes to non-negative,<wbr/> that means that all of the
metadata controls from the request have been applied,<wbr/> all of the
metadata controls from the camera device have been read to the
updated values (into the result),<wbr/> and all of the graphics buffers
corresponding to this result are also synchronized to the request.<wbr/></li>
</ul>
<p><em>Pipeline considerations</em>:</p>
<p>Submitting a request with updated controls relative to the previously
submitted requests may also invalidate the synchronization state
of all the results corresponding to currently in-flight requests.<wbr/></p>
<p>In other words,<wbr/> results for this current request and up to
