Constant Value: 3 (0x00000003)
CONTROL_AE_ANTIBANDING_MODE_OFF
public static final int CONTROL_AE_ANTIBANDING_MODE_OFF
The camera device will not adjust exposure duration to avoid banding problems.
Constant Value: 0 (0x00000000)
CONTROL_AE_MODE_OFF
public static final int CONTROL_AE_MODE_OFF
The camera device's autoexposure routine is disabled.
The application-selected android.sensor.exposureTime
,
android.sensor.sensitivity
and
android.sensor.frameDuration
are used by the camera
device, along with android.flash.* fields, if there's
a flash unit for this camera device.
Note that auto-white balance (AWB) and auto-focus (AF)
behavior is device dependent when AE is in OFF mode.
To have consistent behavior across different devices,
it is recommended to either set AWB and AF to OFF mode
or lock AWB and AF before setting AE to OFF.
See android.control.awbMode
, android.control.afMode
,
android.control.awbLock
, and android.control.afTrigger
for more details.
LEGACY devices do not support the OFF mode and will override attempts to use this value to ON.
See also:
Constant Value: 0 (0x00000000)
CONTROL_AE_MODE_ON
public static final int CONTROL_AE_MODE_ON
The camera device's autoexposure routine is active, with no flash control.
The application's values for
android.sensor.exposureTime
,
android.sensor.sensitivity
, and
android.sensor.frameDuration
are ignored. The
application has control over the various
android.flash.* fields.
If the device supports manual flash strength control, i.e.,
if android.flash.singleStrengthMaxLevel
and
android.flash.torchStrengthMaxLevel
are greater than 1, then
the auto-exposure (AE) precapture metering sequence should be
triggered for the configured flash mode and strength to avoid
the image being incorrectly exposed at different
android.flash.strengthLevel
.

Constant Value: 1 (0x00000001)
CONTROL_AE_MODE_ON_ALWAYS_FLASH
public static final int CONTROL_AE_MODE_ON_ALWAYS_FLASH
Like ON, except that the camera device also controls the camera's flash unit, always firing it for still captures.
The flash may be fired during a precapture sequence
(triggered by android.control.aePrecaptureTrigger
) and
will always be fired for captures for which the
android.control.captureIntent
field is set to
STILL_CAPTURE
See also:
Constant Value: 3 (0x00000003)
CONTROL_AE_MODE_ON_AUTO_FLASH
public static final int CONTROL_AE_MODE_ON_AUTO_FLASH
Like ON, except that the camera device also controls the camera's flash unit, firing it in low-light conditions.
The flash may be fired during a precapture sequence
(triggered by android.control.aePrecaptureTrigger
) and
may be fired for captures for which the
android.control.captureIntent
field is set to
STILL_CAPTURE
See also:
Constant Value: 2 (0x00000002)
CONTROL_AE_MODE_ON_AUTO_FLASH_REDEYE
public static final int CONTROL_AE_MODE_ON_AUTO_FLASH_REDEYE
Like ON_AUTO_FLASH, but with automatic red eye reduction.
If deemed necessary by the camera device, a red eye reduction flash will fire during the precapture sequence.
See also:
Constant Value: 4 (0x00000004)
CONTROL_AE_MODE_ON_EXTERNAL_FLASH
public static final int CONTROL_AE_MODE_ON_EXTERNAL_FLASH
An external flash has been turned on.
It informs the camera device that an external flash has been turned on, and that metering (and continuous focus if active) should be quickly recalculated to account for the external flash. Otherwise, this mode acts like ON.
When the external flash is turned off, AE mode should be changed to one of the other available AE modes.
If the camera device supports AE external flash mode, android.control.aeState
must
be FLASH_REQUIRED after the camera device finishes AE scan and it's too dark without
flash.
Constant Value: 5 (0x00000005)
CONTROL_AE_MODE_ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY
public static final int CONTROL_AE_MODE_ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY
Like 'ON' but applies additional brightness boost in low light scenes.
When the scene lighting conditions are within the range defined by
android.control.lowLightBoostInfoLuminanceRange
this mode will apply additional
brightness boost.
This mode will automatically adjust the intensity of low light boost applied according to the scene lighting conditions. A darker scene will receive more boost while a brighter scene will receive less boost.
This mode can ignore the set target frame rate to allow more light to be captured
which can result in choppier motion. The frame rate can extend to lower than the
android.control.aeAvailableTargetFpsRanges
but will not go below 10 FPS. This mode
can also increase the sensor sensitivity gain which can result in increased luma
and chroma noise. The sensor sensitivity gain can extend to higher values beyond
android.sensor.info.sensitivityRange
. This mode may also apply additional
processing to recover details in dark and bright areas of the image,and noise
reduction at high sensitivity gain settings to manage the trade-off between light
sensitivity and capture noise.
This mode is restricted to two output surfaces. One output surface type can either be SurfaceView or TextureView. Another output surface type can either be MediaCodec or MediaRecorder. This mode cannot be used with a target FPS range higher than 30 FPS.
If the session configuration is not supported, the AE mode reported in the CaptureResult will be 'ON' instead of 'ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY'.
When this AE mode is enabled, the CaptureResult field
android.control.lowLightBoostState
will indicate when low light boost is 'ACTIVE'
or 'INACTIVE'. By default android.control.lowLightBoostState
will be 'INACTIVE'.
The low light boost is 'ACTIVE' once the scene lighting condition is less than the
upper bound lux value defined by android.control.lowLightBoostInfoLuminanceRange
.
This mode will be 'INACTIVE' once the scene lighting condition is greater than the
upper bound lux value defined by android.control.lowLightBoostInfoLuminanceRange
.

public static final int CONTROL_AE_PRECAPTURE_TRIGGER_IDLE
The trigger is idle.
Constant Value: 0 (0x00000000)
CONTROL_AE_PRECAPTURE_TRIGGER_START
public static final int CONTROL_AE_PRECAPTURE_TRIGGER_START
The precapture metering sequence will be started by the camera device.
The exact effect of the precapture trigger depends on the current AE mode and state.
Constant Value: 1 (0x00000001)
CONTROL_AE_STATE_CONVERGED
public static final int CONTROL_AE_STATE_CONVERGED
AE has a good set of control values for the current scene.
See also:
Constant Value: 2 (0x00000002)
CONTROL_AE_STATE_FLASH_REQUIRED

See also:
Constant Value: 4 (0x00000004)
CONTROL_AE_STATE_INACTIVE
public static final int CONTROL_AE_STATE_INACTIVE
AE is off or recently reset.
When a camera device is opened, it starts in this state. This is a transient state, the camera device may skip reporting this state in capture result.
See also:
Constant Value: 0 (0x00000000)
CONTROL_AE_STATE_LOCKED
public static final int CONTROL_AE_STATE_LOCKED
AE has been locked.
See also:
Constant Value: 3 (0x00000003)
CONTROL_AE_STATE_PRECAPTURE
public static final int CONTROL_AE_STATE_PRECAPTURE
AE has been asked to do a precapture sequence and is currently executing it.
Precapture can be triggered through setting
android.control.aePrecaptureTrigger
to START. Currently
active and completed (if it causes camera device internal AE lock) precapture
metering sequence can be canceled through setting
android.control.aePrecaptureTrigger
to CANCEL.
Once PRECAPTURE completes, AE will transition to CONVERGED or FLASH_REQUIRED as appropriate. This is a transient state, the camera device may skip reporting this state in capture result.
Constant Value: 5 (0x00000005)
CONTROL_AE_STATE_SEARCHING
public static final int CONTROL_AE_STATE_SEARCHING
AE doesn't yet have a good set of control values for the current scene.
This is a transient state, the camera device may skip reporting this state in capture result.
See also:
Constant Value: 1 (0x00000001)
CONTROL_AF_MODE_AUTO
public static final int CONTROL_AF_MODE_AUTO
Basic automatic focus mode.
In this mode, the lens does not move unless the autofocus trigger action is called. When that trigger is activated, AF will transition to ACTIVE_SCAN, then to the outcome of the scan (FOCUSED or NOT_FOCUSED).
Always supported if lens is not fixed focus.
Use android.lens.info.minimumFocusDistance
to determine if lens
is fixed-focus.
Triggering AF_CANCEL resets the lens position to default, and sets the AF state to INACTIVE.
Constant Value: 1 (0x00000001)
CONTROL_AF_MODE_CONTINUOUS_PICTURE
public static final int CONTROL_AF_MODE_CONTINUOUS_PICTURE
In this mode, the AF algorithm modifies the lens position continually to attempt to provide a constantly-in-focus image stream.
The focusing behavior should be suitable for still image capture; typically this means focusing as fast as possible. When the AF trigger is not involved, the AF algorithm should start in INACTIVE state, and then transition into PASSIVE_SCAN and PASSIVE_FOCUSED states as appropriate as it attempts to maintain focus. When the AF trigger is activated, the algorithm should finish its PASSIVE_SCAN if active, and then transition into AF_FOCUSED or AF_NOT_FOCUSED as appropriate, and lock the lens position until a cancel AF trigger is received.
When the AF cancel trigger is activated, the algorithm should transition back to INACTIVE and then act as if it has just been started.
See also:
Constant Value: 4 (0x00000004)
CONTROL_AF_MODE_CONTINUOUS_VIDEO
public static final int CONTROL_AF_MODE_CONTINUOUS_VIDEO
In this mode, the AF algorithm modifies the lens position continually to attempt to provide a constantly-in-focus image stream.
The focusing behavior should be suitable for good quality video recording; typically this means slower focus movement and no overshoots. When the AF trigger is not involved, the AF algorithm should start in INACTIVE state, and then transition into PASSIVE_SCAN and PASSIVE_FOCUSED states as appropriate. When the AF trigger is activated, the algorithm should immediately transition into AF_FOCUSED or AF_NOT_FOCUSED as appropriate, and lock the lens position until a cancel AF trigger is received.
Once cancel is received, the algorithm should transition back to INACTIVE and resume passive scan. Note that this behavior is not identical to CONTINUOUS_PICTURE, since an ongoing PASSIVE_SCAN must immediately be canceled.
See also:
Constant Value: 3 (0x00000003)
CONTROL_AF_MODE_EDOF
public static final int CONTROL_AF_MODE_EDOF
Extended depth of field (digital focus) mode.
The camera device will produce images with an extended depth of field automatically; no special focusing operations need to be done before taking a picture.
AF triggers are ignored, and the AF state will always be INACTIVE.
See also:
Constant Value: 5 (0x00000005)
CONTROL_AF_MODE_MACRO
public static final int CONTROL_AF_MODE_MACRO
Close-up focusing mode.
In this mode, the lens does not move unless the autofocus trigger action is called. When that trigger is activated, AF will transition to ACTIVE_SCAN, then to the outcome of the scan (FOCUSED or NOT_FOCUSED). This mode is optimized for focusing on objects very close to the camera.
When that trigger is activated, AF will transition to ACTIVE_SCAN, then to the outcome of the scan (FOCUSED or NOT_FOCUSED). Triggering cancel AF resets the lens position to default, and sets the AF state to INACTIVE.

CONTROL_SCENE_MODE_HDR
public static final int CONTROL_SCENE_MODE_HDR
Turn on a device-specific high dynamic range (HDR) mode.
In this scene mode, the camera device captures images that keep a larger range of scene illumination levels visible in the final image. For example, when taking a picture of a object in front of a bright window, both the object and the scene through the window may be visible when using HDR mode, while in normal AUTO mode, one or the other may be poorly exposed. As a tradeoff, HDR mode generally takes much longer to capture a single image, has no user control, and may have other artifacts depending on the HDR method used.
Therefore, HDR captures operate at a much slower rate than regular captures.
In this mode, on LIMITED or FULL devices, when a request
is made with a android.control.captureIntent
of
STILL_CAPTURE, the camera device will capture an image
using a high dynamic range capture technique. On LEGACY
devices, captures that target a JPEG-format output will
be captured with HDR, and the capture intent is not
relevant.
The HDR capture may involve the device capturing a burst of images internally and combining them into one, or it may involve the device using specialized high dynamic range capture hardware. In all cases, a single image is produced in response to a capture request submitted while in HDR mode.
Since substantial post-processing is generally needed to produce an HDR image, only YUV, PRIVATE, and JPEG outputs are supported for LIMITED/FULL device HDR captures, and only JPEG outputs are supported for LEGACY HDR captures. Using a RAW output for HDR capture is not supported.
Some devices may also support always-on HDR, which applies HDR processing at full frame rate. For these devices, intents other than STILL_CAPTURE will also produce an HDR output with no frame rate impact compared to normal operation, though the quality may be lower than for STILL_CAPTURE intents.
If SCENE_MODE_HDR is used with unsupported output types or capture intents, the images captured will be as if the SCENE_MODE was not enabled at all.
Constant Value: 18 (0x00000012)
CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO
public static final int CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO
This constant was deprecated
in API level 23.
Please refer to this API documentation to find the alternatives
This is deprecated, please use CameraDevice.createConstrainedHighSpeedCaptureSession(List, StateCallback, Handler)
and CameraConstrainedHighSpeedCaptureSession.createHighSpeedRequestList(CaptureRequest)
for high speed video recording.
Optimized for high speed video recording (frame rate >=60fps) use case.
The supported high speed video sizes and fps ranges are specified in
android.control.availableHighSpeedVideoConfigurations. To get desired
output frame rates, the application is only allowed to select video size
and fps range combinations listed in this static metadata. The fps range
can be control via android.control.aeTargetFpsRange
.
In this mode, the camera device will override aeMode, awbMode, and afMode to
ON, ON, and CONTINUOUS_VIDEO, respectively. All post-processing block mode
controls will be overridden to be FAST. Therefore, no manual control of capture
and post-processing parameters is possible. All other controls operate the
same as when android.control.mode
== AUTO. This means that all other
android.control.* fields continue to work, such as
android.control.aeTargetFpsRange
android.control.aeExposureCompensation
android.control.aeLock
android.control.awbLock
android.control.effectMode
android.control.aeRegions
android.control.afRegions
android.control.awbRegions
android.control.afTrigger
android.control.aePrecaptureTrigger
android.control.zoomRatio
Outside of android.control.*, the following controls will work:
android.flash.mode
(automatic flash for still capture will not work since aeMode is ON)android.lens.opticalStabilizationMode
(if it is supported)android.scaler.cropRegion
android.statistics.faceDetectMode
For high speed recording use case, the actual maximum supported frame rate may be lower than what camera can output, depending on the destination Surfaces for the image data. For example, if the destination surface is from video encoder, the application need check if the video encoder is capable of supporting the high frame rate for a given video size, or it will end up with lower recording frame rate. If the destination surface is from preview window, the preview frame rate will be bounded by the screen refresh rate.
The camera device will only support up to 2 output high speed streams (processed non-stalling format defined in android.request.maxNumOutputStreams) in this mode. This control will be effective only if all of below conditions are true:
- The application created no more than maxNumHighSpeedStreams processed non-stalling format output streams, where maxNumHighSpeedStreams is calculated as min(2, android.request.maxNumOutputStreams[Processed (but not-stalling)]).
- The stream sizes are selected from the sizes reported by android.control.availableHighSpeedVideoConfigurations.
- No processed non-stalling or raw streams are configured.
When above conditions are NOT satisfied, the controls of this mode and
android.control.aeTargetFpsRange
will be ignored by the camera device,
the camera device will fall back to android.control.mode
==
AUTO,
and the returned capture result metadata will give the fps range chosen
by the camera device.
Switching into or out of this mode may trigger some camera ISP/sensor reconfigurations, which may introduce extra latency. It is recommended that the application avoids unnecessary scene mode switch as much as possible.

Preview stabilization, where the preview in addition to all other non-RAW streams are stabilized with the same quality of stabilization, is enabled. This mode aims to give clients a 'what you see is what you get' effect. In this mode, the FoV reduction will be a maximum of 20 % both horizontally and vertically (10% from left, right, top, bottom) for the given zoom ratio / crop region.

EDGE_MODE_ZERO_SHUTTER_LAG
public static final int EDGE_MODE_ZERO_SHUTTER_LAG
Edge enhancement is applied at different
levels for different output streams, based on resolution. Streams at maximum recording
resolution (see CameraDevice.createCaptureSession(SessionConfiguration)
)
or below have edge enhancement applied, while higher-resolution streams have no edge
enhancement applied. The level of edge enhancement for low-resolution streams is tuned
so that frame rate is not impacted, and the quality is equal to or better than FAST
(since it is only applied to lower-resolution outputs, quality may improve from FAST).
This mode is intended to be used by applications operating in a zero-shutter-lag mode with YUV or PRIVATE reprocessing, where the application continuously captures high-resolution intermediate buffers into a circular buffer, from which a final image is produced via reprocessing when a user takes a picture. For such a use case, the high-resolution buffers must not have edge enhancement applied to maximize efficiency of preview and to avoid double-applying enhancement when reprocessed, while low-resolution buffers (used for recording or preview, generally) need edge enhancement applied for reasonable preview quality.
This mode is guaranteed to be supported by devices that support either the
YUV_REPROCESSING or PRIVATE_REPROCESSING capabilities
(android.request.availableCapabilities
lists either of those capabilities) and it will
be the default mode for CAMERA3_TEMPLATE_ZERO_SHUTTER_LAG template.

NOISE_REDUCTION_MODE_ZERO_SHUTTER_LAG
public static final int NOISE_REDUCTION_MODE_ZERO_SHUTTER_LAG
Noise reduction is applied at different levels for different output streams,
based on resolution. Streams at maximum recording resolution (see CameraDevice.createCaptureSession(SessionConfiguration)
)
or below have noise reduction applied, while higher-resolution streams have MINIMAL (if
supported) or no noise reduction applied (if MINIMAL is not supported.) The degree of
noise reduction for low-resolution streams is tuned so that frame rate is not impacted,
and the quality is equal to or better than FAST (since it is only applied to
lower-resolution outputs, quality may improve from FAST).
This mode is intended to be used by applications operating in a zero-shutter-lag mode with YUV or PRIVATE reprocessing, where the application continuously captures high-resolution intermediate buffers into a circular buffer, from which a final image is produced via reprocessing when a user takes a picture. For such a use case, the high-resolution buffers must not have noise reduction applied to maximize efficiency of preview and to avoid over-applying noise filtering when reprocessing, while low-resolution buffers (used for recording or preview, generally) need noise reduction applied for reasonable preview quality.
This mode is guaranteed to be supported by devices that support either the

Constant Value: 0 (0x00000000)
REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE
public static final int REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE
The camera device supports capturing high-resolution images at >= 20 frames per second, in at least the uncompressed YUV format, when post-processing settings are set to FAST. Additionally, all image resolutions less than 24 megapixels can be captured at >= 10 frames per second. Here, 'high resolution' means at least 8 megapixels, or the maximum resolution of the device, whichever is smaller.
More specifically, this means that a size matching the camera device's active array
size is listed as a supported size for the ImageFormat.YUV_420_888
format in either StreamConfigurationMap.getOutputSizes(int)
or StreamConfigurationMap.getHighResolutionOutputSizes(int)
,
with a minimum frame duration for that format and size of either <= 1/20 s, or
<= 1/10 s if the image size is less than 24 megapixels, respectively; and
the android.control.aeAvailableTargetFpsRanges
entry lists at least one FPS range
where the minimum FPS is >= 1 / minimumFrameDuration for the maximum-size
YUV_420_888 format. If that maximum size is listed in StreamConfigurationMap.getHighResolutionOutputSizes(int)
,
then the list of resolutions for YUV_420_888 from StreamConfigurationMap.getOutputSizes(int)
contains at
least one resolution >= 8 megapixels, with a minimum frame duration of <= 1/20
s.
If the device supports the ImageFormat.RAW10
, ImageFormat.RAW12
, ImageFormat.Y8
, then those can also be
captured at the same rate as the maximum-size YUV_420_888 resolution is.
If the device supports the PRIVATE_REPROCESSING capability, then the same guarantees
as for the YUV_420_888 format also apply to the ImageFormat.PRIVATE
format.
In addition, the android.sync.maxLatency
field is guaranteed to have a value between 0
and 4, inclusive. android.control.aeLockAvailable
and android.control.awbLockAvailable
are also guaranteed to be true
so burst capture with these two locks ON yields
consistent image output.

REQUEST_AVAILABLE_CAPABILITIES_COLOR_SPACE_PROFILES
public static final int REQUEST_AVAILABLE_CAPABILITIES_COLOR_SPACE_PROFILES
The device supports querying the possible combinations of color spaces, image
formats, and dynamic range profiles supported by the camera and requesting a
particular color space for a session via
SessionConfiguration.setColorSpace(Named)
.
Cameras that enable this capability may or may not also implement dynamic range
profiles. If they don't,
ColorSpaceProfiles.getSupportedDynamicRangeProfiles(Named, int)
will return only
DynamicRangeProfiles.STANDARD
and
ColorSpaceProfiles.getSupportedColorSpacesForDynamicRange(int, long)
will assume support of the
DynamicRangeProfiles.STANDARD
profile in all combinations of color spaces and image formats.
Constant Value: 20 (0x00000014)
REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO
public static final int REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO
The device supports constrained high speed video recording (frame rate >=120fps) use
case. The camera device will support high speed capture session created by CameraDevice.createConstrainedHighSpeedCaptureSession(List, StateCallback, Handler)
, which
only accepts high speed request lists created by CameraConstrainedHighSpeedCaptureSession.createHighSpeedRequestList(CaptureRequest)
.
A camera device can still support high speed video streaming by advertising the high
speed FPS ranges in android.control.aeAvailableTargetFpsRanges
. For this case, all
normal capture request per frame control and synchronization requirements will apply
to the high speed fps ranges, the same as all other fps ranges. This capability
describes the capability of a specialized operating mode with many limitations (see
below), which is only targeted at high speed video recording.
The supported high speed video sizes and fps ranges are specified in StreamConfigurationMap.getHighSpeedVideoFpsRanges()
.
To get desired output frame rates, the application is only allowed to select video
size and FPS range combinations provided by StreamConfigurationMap.getHighSpeedVideoSizes()
. The
fps range can be controlled via android.control.aeTargetFpsRange
.
In this capability, the camera device will override aeMode, awbMode, and afMode to
ON, AUTO, and CONTINUOUS_VIDEO, respectively. All post-processing block mode
controls will be overridden to be FAST. Therefore, no manual control of capture
and post-processing parameters is possible. All other controls operate the
same as when android.control.mode
== AUTO. This means that all other
android.control.* fields continue to work, such as
android.control.aeTargetFpsRange
android.control.aeExposureCompensation
android.control.aeLock
android.control.awbLock
android.control.effectMode
android.control.aeRegions
android.control.afRegions
android.control.awbRegions
android.control.afTrigger
android.control.aePrecaptureTrigger
android.control.zoomRatio
Outside of android.control.*, the following controls will work:
android.flash.mode
(TORCH mode only, automatic flash for still capture will not work since aeMode is ON)android.lens.opticalStabilizationMode
(if it is supported)android.scaler.cropRegion
android.statistics.faceDetectMode
(if it is supported)
For high speed recording use case, the actual maximum supported frame rate may be lower than what camera can output, depending on the destination Surfaces for the image data. For example, if the destination surface is from video encoder, the application need check if the video encoder is capable of supporting the high frame rate for a given video size, or it will end up with lower recording frame rate. If the destination surface is from preview window, the actual preview frame rate will be bounded by the screen refresh rate.
The camera device will only support up to 2 high speed simultaneous output surfaces (preview and recording surfaces) in this mode. Above controls will be effective only if all of below conditions are true:
- The application creates a camera capture session with no more than 2 surfaces via
CameraDevice.createConstrainedHighSpeedCaptureSession(List, StateCallback, Handler)
. The targeted surfaces must be preview surface (either fromSurfaceView
orSurfaceTexture
) or recording surface(either fromMediaRecorder.getSurface()
orMediaCodec.createInputSurface()
). - The stream sizes are selected from the sizes reported by
StreamConfigurationMap.getHighSpeedVideoSizes()
. - The FPS ranges are selected from
StreamConfigurationMap.getHighSpeedVideoFpsRanges()
.
When above conditions are NOT satisfied,
CameraDevice.createConstrainedHighSpeedCaptureSession(List, StateCallback, Handler)
will fail.
Switching to a FPS range that has different maximum FPS may trigger some camera device reconfigurations, which may introduce extra latency. It is recommended that the application avoids unnecessary maximum target FPS changes as much as possible during high speed streaming.

REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT
public static final int REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT
The camera device can produce depth measurements from its field of view.
This capability requires the camera device to support the following:
ImageFormat.DEPTH16
is supported as an output format.ImageFormat.DEPTH_POINT_CLOUD
is optionally supported as an output format.- This camera device, and all camera devices with the same
android.lens.facing
, will list the following calibration metadata entries in bothCameraCharacteristics
andCaptureResult
: - The
android.depth.depthIsExclusive
entry is listed by this device. - As of Android P, the
android.lens.poseReference
entry is listed by this device. - A LIMITED camera with only the DEPTH_OUTPUT capability does not have to support normal YUV_420_888, Y8, JPEG, and PRIV-format outputs. It only has to support the DEPTH16 format.
Generally, depth output operates at a slower frame rate than standard color capture,
so the DEPTH16 and DEPTH_POINT_CLOUD formats will commonly have a stall duration that
should be accounted for (see StreamConfigurationMap.getOutputStallDuration(int, Size)
).
On a device that supports both depth and color-based output, to enable smooth preview,
using a repeating burst is recommended, where a depth-output target is only included
once every N frames, where N is the ratio between preview output rate and depth output
rate, including depth stall time.

REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA
public static final int REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA
The camera device is a logical camera backed by two or more physical cameras.
In API level 28, the physical cameras must also be exposed to the application via
CameraManager.getCameraIdList()
.
Starting from API level 29:
- Some or all physical cameras may not be independently exposed to the application,
in which case the physical camera IDs will not be available in
CameraManager.getCameraIdList()
. But the application can still query the physical cameras' characteristics by callingCameraManager.getCameraCharacteristics(String)
. - If a physical camera is hidden from camera ID list, the mandatory stream
combinations for that physical camera must be supported through the logical camera
using physical streams. One exception is that in API level 30, a physical camera
may become unavailable via
CameraManager.AvailabilityCallback.onPhysicalCameraUnavailable
callback.
Combinations of logical and physical streams, or physical streams from different
physical cameras are not guaranteed. However, if the camera device supports
CameraDevice.isSessionConfigurationSupported
,
application must be able to query whether a stream combination involving physical
streams is supported by calling
CameraDevice.isSessionConfigurationSupported
.
Camera application shouldn't assume that there are at most 1 rear camera and 1 front camera in the system. For an application that switches between front and back cameras, the recommendation is to switch between the first rear camera and the first front camera in the list of supported camera devices.
This capability requires the camera device to support the following:
- The IDs of underlying physical cameras are returned via
CameraCharacteristics.getPhysicalCameraIds()
. - This camera device must list static metadata
android.logicalMultiCamera.sensorSyncType
inCameraCharacteristics
. - The underlying physical cameras' static metadata must list the following entries, so that the application can correlate pixels from the physical streams:
- The SENSOR_INFO_TIMESTAMP_SOURCE of the logical device and physical devices must be the same.
- The logical camera must be LIMITED or higher device.
A logical camera device's dynamic metadata may contain
android.logicalMultiCamera.activePhysicalId
to notify the application of the current
active physical camera Id. An active physical camera is the physical camera from which
the logical camera's main image data outputs (YUV or RAW) and metadata come from.
In addition, this serves as an indication which physical camera is used to output to
a RAW stream, or in case only physical cameras support RAW, which physical RAW stream
the application should request.
Logical camera's static metadata tags below describe the default active physical camera. An active physical camera is default if it's used when application directly uses requests built from a template. All templates will default to the same active physical camera.

The field of view of non-RAW physical streams must not be smaller than that of the non-RAW logical streams, or the maximum field-of-view of the physical camera, whichever is smaller. The application should check the physical capture result metadata for how the physical streams are cropped or zoomed. More specifically, given the physical camera result metadata, the effective horizontal field-of-view of the physical camera is:
fov = 2 * atan2(cropW * sensorW / (2 * zoomRatio * activeArrayW), focalLength)
where the equation parameters are the physical camera's crop region width, physical sensor width, zoom ratio, active array width, and focal length respectively. Typically the physical stream of active physical camera has the same field-of-view as the logical streams. However, the same may not be true for physical streams from non-active physical cameras. For example, if the logical camera has a wide-ultrawide configuration where the wide lens is the default, when the crop region is set to the logical camera's active array size, (and the zoom ratio set to 1.0 starting from Android 11), a physical stream for the ultrawide camera may prefer outputting images with larger field-of-view than that of the wide camera for better stereo matching margin or more robust motion tracking. At the same time, the physical non-RAW streams' field of view must not be smaller than the requested crop region and zoom ratio, as long as it's within the physical lens' capability. For example, for a logical camera with wide-tele lens configuration where the wide lens is the default, if the logical camera's crop region is set to maximum size, and zoom ratio set to 1.0, the physical stream for the tele lens will be configured to its maximum size crop region (no zoom).
Deprecated: Prior to Android 11, the field of view of all non-RAW physical streams cannot be larger than that of non-RAW logical streams. If the logical camera has a wide-ultrawide lens configuration where the wide lens is the default, when the logical camera's crop region is set to maximum size, the FOV of the physical streams for the ultrawide lens will be the same as the logical stream, by making the crop region smaller than its active array size to compensate for the smaller focal length.
For a logical camera, typically the underlying physical cameras have different RAW capabilities (such as resolution or CFA pattern). There are two ways for the application to capture RAW images from the logical camera:
- If the logical camera has RAW capability, the application can create and use RAW streams in the same way as before. In case a RAW stream is configured, to maintain backward compatibility, the camera device makes sure the default active physical camera remains active and does not switch to other physical cameras. (One exception is that, if the logical camera consists of identical image sensors and advertises multiple focalLength due to different lenses, the camera device may generate RAW images from different physical cameras based on the focalLength being set by the application.) This backward-compatible approach usually results in loss of optical zoom, to telephoto lens or to ultrawide lens.
- Alternatively, if supported by the device,
MultiResolutionImageReader
can be used to capture RAW images from one of the underlying physical cameras ( depending on current zoom level). Because different physical cameras may have different RAW characteristics, the application needs to use the characteristics and result metadata of the active physical camera for the relevant RAW metadata.
The capture request and result metadata tags required for backward compatible camera functionalities will be solely based on the logical camera capability. On the other hand, the use of manual capture controls (sensor or post-processing) with a logical camera may result in unexpected behavior when the HAL decides to switch between physical cameras with different characteristics under the hood. For example, when the application manually sets exposure time and sensitivity while zooming in, the brightness of the camera images may suddenly change because HAL switches from one physical camera to the other.

REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR
public static final int REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR
The camera device can be manually controlled (3A algorithms such as auto-exposure, and auto-focus can be bypassed). The camera device supports basic manual control of the sensor image acquisition related stages. This means the following controls are guaranteed to be supported:
- Manual frame duration control
- Manual exposure control
- Manual sensitivity control
- Manual lens control (if the lens is adjustable)
- android.lens.*
- Manual flash control (if a flash unit is present)
- android.flash.*

A given camera device may also support additional manual sensor controls, but this capability only covers the above list of controls.
If this is supported, android.scaler.streamConfigurationMap
will
additionally return a min frame duration that is greater than
zero for each supported size-format combination.
For camera devices with LOGICAL_MULTI_CAMERA capability, when the underlying active physical camera switches, exposureTime, sensitivity, and lens properties may change even if AE/AF is locked. However, the overall auto exposure and auto focus experience for users will be consistent. Refer to LOGICAL_MULTI_CAMERA capability for details.

public static final int REQUEST_AVAILABLE_CAPABILITIES_MONOCHROME
The camera device is a monochrome camera that doesn't contain a color filter array, and for YUV_420_888 stream, the pixel values on U and V planes are all 128.
A MONOCHROME camera must support the guaranteed stream combinations required for
its device level and capabilities. Additionally, if the monochrome camera device
supports Y8 format, all mandatory stream combination requirements related to YUV_420_888
apply
to Y8
as well. There are no
mandatory stream combination requirements with regard to
Y8
for Bayer camera devices.
Starting from Android Q, the SENSOR_INFO_COLOR_FILTER_ARRANGEMENT of a MONOCHROME camera will be either MONO or NIR.
Constant Value: 12 (0x0000000c)
REQUEST_AVAILABLE_CAPABILITIES_MOTION_TRACKING
public static final int REQUEST_AVAILABLE_CAPABILITIES_MOTION_TRACKING
The camera device supports the MOTION_TRACKING value for
android.control.captureIntent
, which limits maximum exposure time to 20 ms.
This limits the motion blur of capture images, resulting in better image tracking results for use cases such as image stabilization or augmented reality.
Constant Value: 10 (0x0000000a)
REQUEST_AVAILABLE_CAPABILITIES_OFFLINE_PROCESSING
public static final int REQUEST_AVAILABLE_CAPABILITIES_OFFLINE_PROCESSING
The camera device supports the OFFLINE_PROCESSING use case.
With OFFLINE_PROCESSING capability, the application can switch an ongoing capture session to offline mode by calling the CameraCaptureSession#switchToOffline method and specify streams to be kept in offline mode. The camera will then stop currently active repeating requests, prepare for some requests to go into offline mode, and return an offline session object. After the switchToOffline call returns, the original capture session is in closed state as if the CameraCaptureSession#close method has been called. In the offline mode, all inflight requests will continue to be processed in the background, and the application can immediately close the camera or create a new capture session without losing those requests' output images and capture results.
While the camera device is processing offline requests, it might not be able to support all stream configurations it can support without offline requests. When that happens, the createCaptureSession method call will fail. The following stream configurations are guaranteed to work without hitting the resource busy exception:
- One ongoing offline session: target one output surface of YUV or JPEG format, any resolution.
- The active camera capture session:
- One preview surface (SurfaceView or SurfaceTexture) up to 1920 width
- One YUV ImageReader surface up to 1920 width
- One Jpeg ImageReader, any resolution: the camera device is allowed to slow down JPEG output speed by 50% if there is any ongoing offline session.
- If the device supports PRIVATE_REPROCESSING, one pair of ImageWriter/ImageReader surfaces of private format, with the same resolution that is larger or equal to the JPEG ImageReader resolution above.
- Alternatively, the active camera session above can be replaced by an legacy
Camera
with the following parameter settings:- Preview size up to 1920 width
- Preview callback size up to 1920 width
- Video size up to 1920 width
- Picture size, any resolution: the camera device is allowed to slow down JPEG output speed by 50% if there is any ongoing offline session.

public static final int REQUEST_AVAILABLE_CAPABILITIES_REMOSAIC_REPROCESSING
The device supports reprocessing from the RAW_SENSOR
format with a bayer pattern
given by android.sensor.info.binningFactor
(m x n group of pixels with the same
color filter) to a remosaiced regular bayer pattern.
This capability will only be present for devices with
REQUEST_AVAILABLE_CAPABILITIES_ULTRA_HIGH_RESOLUTION_SENSOR
capability. When
REQUEST_AVAILABLE_CAPABILITIES_ULTRA_HIGH_RESOLUTION_SENSOR
devices do not advertise this capability,
ImageFormat.RAW_SENSOR
images will already have a
regular bayer pattern.
If a RAW_SENSOR
stream is requested along with another non-RAW stream in a
CaptureRequest
(if multiple streams are supported
when android.sensor.pixelMode
is set to
SENSOR_PIXEL_MODE_MAXIMUM_RESOLUTION
),
the RAW_SENSOR
stream will have a regular bayer pattern.
This capability requires the camera device to support the following :

Constant Value: 13 (0x0000000d)
REQUEST_AVAILABLE_CAPABILITIES_STREAM_USE_CASE
public static final int REQUEST_AVAILABLE_CAPABILITIES_STREAM_USE_CASE
The camera device supports selecting a per-stream use case via
OutputConfiguration.setStreamUseCase(long)
so that the device can optimize camera pipeline parameters such as tuning, sensor
mode, or ISP settings for a specific user scenario.
Some sample usages of this capability are:
- Distinguish high quality YUV captures from a regular YUV stream where the image quality may not be as good as the JPEG stream, or
- Use one stream to serve multiple purposes: viewfinder, video recording and still capture. This is common with applications that wish to apply edits equally to preview, saved images, and saved videos.
This capability requires the camera device to support the following stream use cases:
- DEFAULT for backward compatibility where the application doesn't set a stream use case
- PREVIEW for live viewfinder and in-app image analysis
- STILL_CAPTURE for still photo capture
- VIDEO_RECORD for recording video clips
- PREVIEW_VIDEO_STILL for one single stream used for viewfinder, video recording, and still capture.
- VIDEO_CALL for long running video calls

REQUEST_AVAILABLE_CAPABILITIES_YUV_REPROCESSING
public static final int REQUEST_AVAILABLE_CAPABILITIES_YUV_REPROCESSING
The camera device supports the YUV_420_888 reprocessing use case, similar as PRIVATE_REPROCESSING, This capability requires the camera device to support the following:
- One input stream is supported, that is,
.android.request.maxNumInputStreams
== 1 ImageFormat.YUV_420_888
is supported as an output/input format, that is, YUV_420_888 is included in the lists of formats returned byStreamConfigurationMap.getInputFormats()
andStreamConfigurationMap.getOutputFormats()
.StreamConfigurationMap.getValidOutputFormatsForInput(int)
returns non-empty int[] for each supported input format returned byStreamConfigurationMap.getInputFormats()
.- Each size returned by
getInputSizes(YUV_420_888)
is also included ingetOutputSizes(YUV_420_888)
- Using
ImageFormat.YUV_420_888
does not cause a frame rate drop relative to the sensor's maximum capture rate (at that resolution). ImageFormat.YUV_420_888
will be reprocessable into bothImageFormat.YUV_420_888
andImageFormat.JPEG
formats.- The maximum available resolution for
ImageFormat.YUV_420_888
streams (both input/output) will match the maximum available resolution ofImageFormat.JPEG
streams. - For a MONOCHROME camera with Y8 format support, all the requirements mentioned above for YUV_420_888 apply for Y8 format as well.
- Static metadata

SCALER_AVAILABLE_STREAM_USE_CASES_CROPPED_RAW
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_CROPPED_RAW
Cropped RAW stream when the client chooses to crop the field of view.
Certain types of image sensors can run in binned modes in order to improve signal to noise ratio while capturing frames. However, at certain zoom levels and / or when other scene conditions are deemed fit, the camera sub-system may choose to un-bin and remosaic the sensor's output. This results in a RAW frame which is cropped in field of view and yet has the same number of pixels as full field of view RAW, thereby improving image detail.
The resultant field of view of the RAW stream will be greater than or equal to
croppable non-RAW streams. The effective crop region for this RAW stream will be
reflected in the CaptureResult key android.scaler.rawCropRegion
.
If this stream use case is set on a non-RAW stream, i.e. not one of :
session configuration is not guaranteed to succeed.
This stream use case may not be supported on some devices.

SCALER_AVAILABLE_STREAM_USE_CASES_DEFAULT
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_DEFAULT
Default stream use case.
This use case is the same as when the application doesn't set any use case for the stream. The camera device uses the properties of the output target, such as format, dataSpace, or surface class type, to optimize the image processing pipeline.
Constant Value: 0 (0x00000000)
SCALER_AVAILABLE_STREAM_USE_CASES_PREVIEW
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_PREVIEW
Live stream shown to the user.
Optimized for performance and usability as a viewfinder, but not necessarily for image quality. The output is not meant to be persisted as saved images or video.
No stall if android.control.* are set to FAST. There may be stall if they are set to HIGH_QUALITY. This use case has the same behavior as the default SurfaceView and SurfaceTexture targets. Additionally, this use case can be used for in-app image analysis.
Constant Value: 1 (0x00000001)
SCALER_AVAILABLE_STREAM_USE_CASES_PREVIEW_VIDEO_STILL
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_PREVIEW_VIDEO_STILL
One single stream used for combined purposes of preview, video, and still capture.
For such multi-purpose streams, the camera device aims to make the best tradeoff between the individual use cases. For example, the STILL_CAPTURE use case by itself may have stalls for achieving best image quality. But if combined with PREVIEW and VIDEO_RECORD, the camera device needs to trade off the additional image processing for speed so that preview and video recording aren't slowed down.
Similarly, VIDEO_RECORD may produce frames with a substantial lag, but PREVIEW_VIDEO_STILL must have minimal output delay. This means that to enable video stabilization with this use case, the device must support and the app must select the PREVIEW_STABILIZATION mode for video stabilization.
Constant Value: 4 (0x00000004)
SCALER_AVAILABLE_STREAM_USE_CASES_STILL_CAPTURE
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_STILL_CAPTURE
Still photo capture.
Optimized for high-quality high-resolution capture, and not expected to maintain preview-like frame rates.
The stream may have stalls regardless of whether android.control.* is HIGH_QUALITY. This use case has the same behavior as the default JPEG and RAW related formats.
Constant Value: 2 (0x00000002)
SCALER_AVAILABLE_STREAM_USE_CASES_VIDEO_CALL
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_VIDEO_CALL
Long-running video call optimized for both power efficiency and video quality.
The camera sensor may run in a lower-resolution mode to reduce power consumption at the cost of some image and digital zoom quality. Unlike VIDEO_RECORD, VIDEO_CALL outputs are expected to work in dark conditions, so are usually accompanied with variable frame rate settings to allow sufficient exposure time in low light.
Constant Value: 5 (0x00000005)
SCALER_AVAILABLE_STREAM_USE_CASES_VIDEO_RECORD
public static final int SCALER_AVAILABLE_STREAM_USE_CASES_VIDEO_RECORD
Recording video clips.
Optimized for high-quality video capture, including high-quality image stabilization if supported by the device and enabled by the application. As a result, may produce output frames with a substantial lag from real time, to allow for highest-quality stabilization or other processing. As such, such an output is not suitable for drawing to screen directly, and is expected to be persisted to disk or similar for later playback or processing. Only streams that set the VIDEO_RECORD use case are guaranteed to have video stabilization applied when the video stabilization control is set to ON, as opposed to PREVIEW_STABILIZATION.

Constant Value: 1 (0x00000001)
SCALER_ROTATE_AND_CROP_AUTO
public static final int SCALER_ROTATE_AND_CROP_AUTO
The camera API automatically selects the best concrete value for rotate-and-crop based on the application's support for resizability and the current multi-window mode.
If the application does not support resizing but the display mode for its main
Activity is not in a typical orientation, the camera API will set ROTATE_AND_CROP_90
or some other supported rotation value, depending on device configuration,
to ensure preview and captured images are correctly shown to the user. Otherwise,
ROTATE_AND_CROP_NONE
will be selected.
When a value other than NONE is selected, several metadata fields will also be parsed differently to ensure that coordinates are correctly handled for features like drawing face detection boxes or passing in tap-to-focus coordinates. The camera API will convert positions in the active array coordinate system to/from the cropped-and-rotated coordinate system to make the operation transparent for applications.
No coordinate mapping will be done when the application selects a non-AUTO mode.

Constant Value: 1 (0x00000001)
SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_MONO
public static final int SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_MONO
Sensor doesn't have any Bayer color filter. Such sensor captures visible light in monochrome. The exact weighting and wavelengths captured is not specified, but generally only includes the visible frequencies. This value implies a MONOCHROME camera.
Constant Value: 5 (0x00000005)
SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_NIR
public static final int SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_NIR
Sensor has a near infrared filter capturing light with wavelength between roughly 750nm and 1400nm, and the same filter covers the whole sensor array. This value implies a MONOCHROME camera.
Constant Value: 6 (0x00000006)
SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_RGB
public static final int SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_RGB
Sensor is not Bayer; output has 3 16-bit values for each pixel, instead of just 1 16-bit value per pixel.
Constant Value: 4 (0x00000004)
SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_RGGB
public static final int SENSOR_INFO_COLOR_FILTER_ARRANGEMENT_RGGB
Constant Value: 0 (0x00000000)
SENSOR_INFO_TIMESTAMP_SOURCE_REALTIME
public static final int SENSOR_INFO_TIMESTAMP_SOURCE_REALTIME
Timestamps from android.sensor.timestamp
are in the same timebase as
SystemClock.elapsedRealtimeNanos()
,
and they can be compared to other timestamps using that base.
When buffers from a REALTIME device are passed directly to a video encoder from the
camera, automatic compensation is done to account for differing timebases of the
audio and camera subsystems. If the application is receiving buffers and then later
sending them to a video encoder or other application where they are compared with
audio subsystem timestamps or similar, this compensation is not present. In those
cases, applications need to adjust the timestamps themselves. Since SystemClock.elapsedRealtimeNanos()
and SystemClock.uptimeMillis()
only diverge while the device is asleep, an
offset between the two sources can be measured once per active session and applied
to timestamps for sufficient accuracy for A/V sync.
Constant Value: 1 (0x00000001)
SENSOR_INFO_TIMESTAMP_SOURCE_UNKNOWN
public static final int SENSOR_INFO_TIMESTAMP_SOURCE_UNKNOWN
Timestamps from android.sensor.timestamp
are in nanoseconds and monotonic, but can
not be compared to timestamps from other subsystems (e.g. accelerometer, gyro etc.),
or other instances of the same or different camera devices in the same system with
accuracy. However, the timestamps are roughly in the same timebase as
SystemClock.uptimeMillis()
. The accuracy is sufficient for tasks
like A/V synchronization for video recording, at least, and the timestamps can be
directly used together with timestamps from the audio subsystem for that task.
Timestamps between streams and results for a single camera instance are comparable, and the timestamps for all buffers and the result metadata generated by a single capture are identical.
Constant Value: 0 (0x00000000)
SENSOR_PIXEL_MODE_DEFAULT
public static final int SENSOR_PIXEL_MODE_DEFAULT
This is the default sensor pixel mode.

SENSOR_READOUT_TIMESTAMP_HARDWARE
public static final int SENSOR_READOUT_TIMESTAMP_HARDWARE
This camera device supports the onReadoutStarted callback as well as outputting readout timestamps. The readout timestamp is generated by the camera hardware and it has the same accuracy and timing characteristics of the start-of-exposure time.

SENSOR_TEST_PATTERN_MODE_COLOR_BARS
public static final int SENSOR_TEST_PATTERN_MODE_COLOR_BARS
All pixel data is replaced with an 8-bar color pattern.
The vertical bars (left-to-right) are as follows:
- 100% white
- yellow
- cyan
- green
- magenta
- red
- blue
- black
In general the image would look like the following:
W Y C G M R B K
W Y C G M R B K
W Y C G M R B K
W Y C G M R B K
W Y C G M R B K
. . . . . . . .
. . . . . . . .
. . . . . . . .
(B = Blue, K = Black)
Each bar should take up 1/8 of the sensor pixel array width. When this is not possible, the bar size should be rounded down to the nearest integer and the pattern can repeat on the right side.
Each bar's height must always take up the full sensor pixel array height.
Each pixel in this test pattern must be set to either 0% intensity or 100% intensity.
See also:
Constant Value: 2 (0x00000002)
SENSOR_TEST_PATTERN_MODE_COLOR_BARS_FADE_TO_GRAY
public static final int SENSOR_TEST_PATTERN_MODE_COLOR_BARS_FADE_TO_GRAY
The test pattern is similar to COLOR_BARS, except that each bar should start at its specified color at the top, and fade to gray at the bottom.
Furthermore each bar is further subdivided into a left and right half. The left half should have a smooth gradient, and the right half should have a quantized gradient.
In particular, the right half's should consist of blocks of the same color for 1/16th active sensor pixel array width.
The least significant bits in the quantized gradient should be copied from the most significant bits of the smooth gradient.
The height of each bar should always be a multiple of 128. When this is not the case, the pattern should repeat at the bottom of the image.

Constant Value: 3 (0x00000003)
SENSOR_TEST_PATTERN_MODE_CUSTOM1

SENSOR_TEST_PATTERN_MODE_PN9
public static final int SENSOR_TEST_PATTERN_MODE_PN9
All pixel data is replaced by a pseudo-random sequence generated from a PN9 512-bit sequence (typically implemented in hardware with a linear feedback shift register).
The generator should be reset at the beginning of each frame, and thus each subsequent raw frame with this test pattern should be exactly the same as the last.

SENSOR_TEST_PATTERN_MODE_SOLID_COLOR
public static final int SENSOR_TEST_PATTERN_MODE_SOLID_COLOR

= [0, 0xFFFFFFFF, 0xFFFFFFFF, 0]
All green pixels are 100% green. All red/blue pixels are black.
android.sensor.testPatternData
= [0xFFFFFFFF, 0, 0xFFFFFFFF, 0]
All red pixels are 100% red. Only the odd green pixels are 100% green. All blue pixels are 100% black.
