COLOR_CORRECTION_ABERRATION_MODE_FAST

int COLOR_CORRECTION_ABERRATION_MODE_FAST

Aberration correction will not slow down capture rate relative to sensor raw output.

Constant Value: 1 (0x00000001)

COLOR_CORRECTION_ABERRATION_MODE_HIGH_QUALITY

int COLOR_CORRECTION_ABERRATION_MODE_HIGH_QUALITY

Aberration correction operates at improved quality but the capture rate might be reduced (relative to sensor raw output rate)

Constant Value: 2 (0x00000002)

COLOR_CORRECTION_ABERRATION_MODE_OFF

int COLOR_CORRECTION_ABERRATION_MODE_OFF

No aberration correction is applied.

Constant Value: 0 (0x00000000)

COLOR_CORRECTION_MODE_FAST

int COLOR_CORRECTION_MODE_FAST

Color correction processing must not slow down capture rate relative to sensor raw output.

Advanced white balance adjustments above and beyond the specified white balance pipeline may be applied.

If AWB is enabled with android.control.awbMode != OFF, then the camera device uses the last frame's AWB values (or defaults if AWB has never been run).

Constant Value: 1 (0x00000001)

COLOR_CORRECTION_MODE_HIGH_QUALITY

int COLOR_CORRECTION_MODE_HIGH_QUALITY

Color correction processing operates at improved quality but the capture rate might be reduced (relative to sensor raw output rate)

Advanced white balance adjustments above and beyond the specified white balance pipeline may be applied.

If AWB is enabled with android.control.awbMode != OFF, then the camera device uses the last frame's AWB values (or defaults if AWB has never been run).

Constant Value: 2 (0x00000002)

COLOR_CORRECTION_MODE_TRANSFORM_MATRIX

int COLOR_CORRECTION_MODE_TRANSFORM_MATRIX

Use the android.colorCorrection.transform matrix and android.colorCorrection.gains to do color conversion.

All advanced white balance adjustments (not specified by our white balance pipeline) must be disabled.

If AWB is enabled with android.control.awbMode != OFF, then TRANSFORM_MATRIX is ignored. The camera device will override this value to either FAST or HIGH_QUALITY.

Constant Value: 0 (0x00000000)

CONTROL_AE_ANTIBANDING_MODE_50HZ

int CONTROL_AE_ANTIBANDING_MODE_50HZ

Constant Value: 3 (0x00000003)

CONTROL_AE_ANTIBANDING_MODE_OFF

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

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.

Constant Value: 0 (0x00000000)

CONTROL_AE_MODE_ON

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.

Constant Value: 1 (0x00000001)

CONTROL_AE_MODE_ON_ALWAYS_FLASH

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

Constant Value: 3 (0x00000003)

CONTROL_AE_MODE_ON_AUTO_FLASH

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.

Constant Value: 2 (0x00000002)

CONTROL_AE_MODE_ON_AUTO_FLASH_REDEYE

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.

Constant Value: 4 (0x00000004)

CONTROL_AE_PRECAPTURE_TRIGGER_CANCEL

int CONTROL_AE_PRECAPTURE_TRIGGER_CANCEL

The camera device will cancel any currently active or completed precapture metering sequence, the auto-exposure routine will return to its initial state.

Constant Value: 2 (0x00000002)

The trigger is idle.

Constant Value: 0 (0x00000000)

CONTROL_AE_PRECAPTURE_TRIGGER_START

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

int CONTROL_AE_STATE_CONVERGED

AE has a good set of control values for the current scene.

Constant Value: 2 (0x00000002)

CONTROL_AE_STATE_FLASH_REQUIRED

int CONTROL_AE_STATE_FLASH_REQUIRED

AE has a good set of control values, but flash needs to be fired for good quality still capture.

Constant Value: 4 (0x00000004)

CONTROL_AE_STATE_INACTIVE

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.

Constant Value: 0 (0x00000000)

CONTROL_AE_STATE_LOCKED

int CONTROL_AE_STATE_LOCKED

AE has been locked.

Constant Value: 3 (0x00000003)

CONTROL_AE_STATE_PRECAPTURE

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

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.

Constant Value: 1 (0x00000001)

CONTROL_AF_MODE_AUTO

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

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.

Constant Value: 4 (0x00000004)

CONTROL_AF_MODE_CONTINUOUS_VIDEO

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.

Constant Value: 3 (0x00000003)

CONTROL_AF_MODE_EDOF

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.

Constant Value: 5 (0x00000005)

CONTROL_AF_MODE_MACRO

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.

Constant Value: 2 (0x00000002)

CONTROL_AF_MODE_OFF

int CONTROL_AF_MODE_OFF

The auto-focus routine does not control the lens; android.lens.focusDistance is controlled by the application.

Constant Value: 0 (0x00000000)

CONTROL_AF_STATE_ACTIVE_SCAN

int CONTROL_AF_STATE_ACTIVE_SCAN

AF is performing an AF scan because it was triggered by AF trigger.

Constant Value: 3 (0x00000003)

CONTROL_AF_STATE_FOCUSED_LOCKED

int CONTROL_AF_STATE_FOCUSED_LOCKED

AF believes it is focused correctly and has locked focus.

This state is reached only after an explicit START AF trigger has been sent (android.control.afTrigger), when good focus has been obtained.

The lens will remain stationary until the AF mode (android.control.afMode) is changed or a new AF trigger is sent to the camera device (android.control.afTrigger).

Constant Value: 4 (0x00000004)

CONTROL_AF_STATE_INACTIVE

int CONTROL_AF_STATE_INACTIVE

AF is off or has not yet tried to scan/been asked to scan.

Constant Value: 0 (0x00000000)

CONTROL_AF_STATE_NOT_FOCUSED_LOCKED

int CONTROL_AF_STATE_NOT_FOCUSED_LOCKED

AF has failed to focus successfully and has locked focus.

This state is reached only after an explicit START AF trigger has been sent (android.control.afTrigger), when good focus cannot be obtained.

Constant Value: 1 (0x00000001)

CONTROL_AF_STATE_PASSIVE_UNFOCUSED

int CONTROL_AF_STATE_PASSIVE_UNFOCUSED

AF finished a passive scan without finding focus, and may restart scanning at any time.

Only used by CONTINUOUS_* AF modes. This is a transient state, the camera device may skip reporting this state in capture result.

CONTROL_MODE_OFF

int CONTROL_MODE_OFF

Full application control of pipeline.

All control by the device's metering and focusing (3A) routines is disabled, and no other settings in android.control.* have any effect, except that android.control.captureIntent may be used by the camera device to select post-processing values for processing blocks that do not allow for manual control, or are not exposed by the camera API.

However, the camera device's 3A routines may continue to collect statistics and update their internal state so that when control is switched to AUTO mode, good control values can be immediately applied.

Constant Value: 0 (0x00000000)

CONTROL_MODE_OFF_KEEP_STATE

int CONTROL_MODE_OFF_KEEP_STATE

Same as OFF mode, except that this capture will not be used by camera device background auto-exposure, auto-white balance and auto-focus algorithms (3A) to update their statistics.

CONTROL_SCENE_MODE_FACE_PRIORITY

int CONTROL_SCENE_MODE_FACE_PRIORITY

If face detection support exists, use face detection data for auto-focus, auto-white balance, and auto-exposure routines.

If face detection statistics are disabled (i.e. android.statistics.faceDetectMode is set to OFF), this should still operate correctly (but will not return face detection statistics to the framework).

Unlike the other scene modes, android.control.aeMode, android.control.awbMode, and android.control.afMode remain active when FACE_PRIORITY is set.

Constant Value: 1 (0x00000001)

CONTROL_SCENE_MODE_FIREWORKS

int CONTROL_SCENE_MODE_FIREWORKS

Optimized for nighttime photos of fireworks.

Constant Value: 12 (0x0000000c)

CONTROL_SCENE_MODE_HDR

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)

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

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 satistied, 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 choosen 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.

EDGE_MODE_FAST

int EDGE_MODE_FAST

Constant Value: 0 (0x00000000)

EDGE_MODE_ZERO_SHUTTER_LAG

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 createCaptureSession(List, CameraCaptureSession.StateCallback, Handler)) 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.

Constant Value: 0 (0x00000000)

INFO_SUPPORTED_HARDWARE_LEVEL_3

int INFO_SUPPORTED_HARDWARE_LEVEL_3

This camera device is capable of YUV reprocessing and RAW data capture, in addition to FULL-level capabilities.

The stream configurations listed in the LEVEL_3, RAW, FULL, LEGACY and LIMITED tables in the createCaptureSession documentation are guaranteed to be supported.

The following additional capabilities are guaranteed to be supported:

• YUV_REPROCESSING capability (android.request.availableCapabilities contains YUV_REPROCESSING)
• RAW capability (android.request.availableCapabilities contains RAW)

Constant Value: 3 (0x00000003)

INFO_SUPPORTED_HARDWARE_LEVEL_FULL

int INFO_SUPPORTED_HARDWARE_LEVEL_FULL

This camera device is capable of supporting advanced imaging applications.

The stream configurations listed in the FULL, LEGACY and LIMITED tables in the createCaptureSession documentation are guaranteed to be supported.

A FULL device will support below capabilities:

• BURST_CAPTURE capability (android.request.availableCapabilities contains BURST_CAPTURE)
• Per frame control (android.sync.maxLatency == PER_FRAME_CONTROL)
• Manual sensor control (android.request.availableCapabilities contains MANUAL_SENSOR)
• Manual post-processing control (android.request.availableCapabilities contains MANUAL_POST_PROCESSING)
• The required exposure time range defined in android.sensor.info.exposureTimeRange
• The required maxFrameDuration defined in android.sensor.info.maxFrameDuration

Note: Pre-API level 23, FULL devices also supported arbitrary cropping region (android.scaler.croppingType == FREEFORM); this requirement was relaxed in API level 23, and FULL devices may only support CENTERED cropping.

Constant Value: 1 (0x00000001)

INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY

int INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY

This camera device is running in backward compatibility mode.

Only the stream configurations listed in the LEGACY table in the createCaptureSession documentation are supported.

A LEGACY device does not support per-frame control, manual sensor control, manual post-processing, arbitrary cropping regions, and has relaxed performance constraints. No additional capabilities beyond BACKWARD_COMPATIBLE will ever be listed by a LEGACY device in android.request.availableCapabilities.

In addition, the android.control.aePrecaptureTrigger is not functional on LEGACY devices. Instead, every request that includes a JPEG-format output target is treated as triggering a still capture, internally executing a precapture trigger. This may fire the flash for flash power metering during precapture, and then fire the flash for the final capture, if a flash is available on the device and the AE mode is set to enable the flash.

Constant Value: 2 (0x00000002)

INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED

int INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED

This camera device does not have enough capabilities to qualify as a FULL device or better.

Only the stream configurations listed in the LEGACY and LIMITED tables in the createCaptureSession documentation are guaranteed to be supported.

All LIMITED devices support the BACKWARDS_COMPATIBLE capability, indicating basic support for color image capture. The only exception is that the device may alternatively support only the DEPTH_OUTPUT capability, if it can only output depth measurements and not color images.

LIMITED devices and above require the use of android.control.aePrecaptureTrigger to lock exposure metering (and calculate flash power, for cameras with flash) before capturing a high-quality still image.

A LIMITED device that only lists the BACKWARDS_COMPATIBLE capability is only required to support full-automatic operation and post-processing (OFF is not supported for android.control.aeMode, android.control.afMode, or android.control.awbMode)

Additional capabilities may optionally be supported by a LIMITED-level device, and can be checked for in android.request.availableCapabilities.

Constant Value: 0 (0x00000000)

Constant Value: 0 (0x00000000)

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_APPROXIMATE

int LENS_INFO_FOCUS_DISTANCE_CALIBRATION_APPROXIMATE

The lens focus distance is measured in diopters.

However, setting the lens to the same focus distance on separate occasions may result in a different real focus distance, depending on factors such as the orientation of the device, the age of the focusing mechanism, and the device temperature.

Constant Value: 1 (0x00000001)

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_CALIBRATED

int LENS_INFO_FOCUS_DISTANCE_CALIBRATION_CALIBRATED

The lens focus distance is measured in diopters, and is calibrated.

The lens mechanism is calibrated so that setting the same focus distance is repeatable on multiple occasions with good accuracy, and the focus distance corresponds to the real physical distance to the plane of best focus.

Constant Value: 2 (0x00000002)

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_UNCALIBRATED

int LENS_INFO_FOCUS_DISTANCE_CALIBRATION_UNCALIBRATED

The lens focus distance is not accurate, and the units used for android.lens.focusDistance do not correspond to any physical units.

Setting the lens to the same focus distance on separate occasions may result in a different real focus distance, depending on factors such as the orientation of the device, the age of the focusing mechanism, and the device temperature. The focus distance value will still be in the range of [0, android.lens.info.minimumFocusDistance], where 0 represents the farthest focus.

Constant Value: 0 (0x00000000)

LENS_OPTICAL_STABILIZATION_MODE_OFF

int LENS_OPTICAL_STABILIZATION_MODE_OFF

Optical stabilization is unavailable.

Constant Value: 0 (0x00000000)

Constant Value: 1 (0x00000001)

LENS_STATE_MOVING

int LENS_STATE_MOVING

One or several of the lens parameters (android.lens.focalLength, android.lens.focusDistance, android.lens.filterDensity or android.lens.aperture) is currently changing.

Constant Value: 1 (0x00000001)

LENS_STATE_STATIONARY

int LENS_STATE_STATIONARY

The lens parameters (android.lens.focalLength, android.lens.focusDistance, android.lens.filterDensity and android.lens.aperture) are not changing.

Constant Value: 0 (0x00000000)

NOISE_REDUCTION_MODE_FAST

int NOISE_REDUCTION_MODE_FAST

Noise reduction is applied without reducing frame rate relative to sensor output. It may be the same as OFF if noise reduction will reduce frame rate relative to sensor.

Constant Value: 1 (0x00000001)

NOISE_REDUCTION_MODE_HIGH_QUALITY

int NOISE_REDUCTION_MODE_HIGH_QUALITY

High-quality noise reduction is applied, at the cost of possibly reduced frame rate relative to sensor output.

Constant Value: 2 (0x00000002)

NOISE_REDUCTION_MODE_MINIMAL

int NOISE_REDUCTION_MODE_MINIMAL

MINIMAL noise reduction is applied without reducing frame rate relative to sensor output.

Constant Value: 3 (0x00000003)

NOISE_REDUCTION_MODE_OFF

int NOISE_REDUCTION_MODE_OFF

No noise reduction is applied.

Constant Value: 0 (0x00000000)

NOISE_REDUCTION_MODE_ZERO_SHUTTER_LAG

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 createCaptureSession(List, CameraCaptureSession.StateCallback, Handler)) 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 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.

Constant Value: 4 (0x00000004)

REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE

int REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE

The minimal set of capabilities that every camera device (regardless of android.info.supportedHardwareLevel) supports.

This capability is listed by all normal devices, and indicates that the camera device has a feature set that's comparable to the baseline requirements for the older android.hardware.Camera API.

Devices with the DEPTH_OUTPUT capability might not list this capability, indicating that they support only depth measurement, not standard color output.

Constant Value: 0 (0x00000000)

REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE

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, maximum-resolution images 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 YUV_420_888 format in either getOutputSizes(int) or getHighResolutionOutputSizes(int), with a minimum frame duration for that format and size of either <= 1/20 s, or <= 1/10 s, 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 getHighResolutionOutputSizes(int), then the list of resolutions for YUV_420_888 from getOutputSizes(int) contains at least one resolution >= 8 megapixels, with a minimum frame duration of <= 1/20 s.

If the device supports the RAW10, RAW12, 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 PRIVATE format.

In addition, the android.sync.maxLatency field is guaranted 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.

Constant Value: 6 (0x00000006)

REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO

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 createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler), which only accepts high speed request lists created by 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 getHighSpeedVideoFpsRanges(). To get desired output frame rates, the application is only allowed to select video size and FPS range combinations provided by 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

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 createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler). The targeted surfaces must be preview surface (either from SurfaceView or SurfaceTexture) or recording surface(either from getSurface() or createInputSurface()).
• The stream sizes are selected from the sizes reported by getHighSpeedVideoSizes().
• The FPS ranges are selected from getHighSpeedVideoFpsRanges().

When above conditions are NOT satistied, createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.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.

Constant Value: 9 (0x00000009)

REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT

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:

• DEPTH16 is supported as an output format.
• 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 entries in both CameraCharacteristics and CaptureResult:
  • android.lens.poseTranslation
  • android.lens.poseRotation
  • android.lens.intrinsicCalibration
  • android.lens.radialDistortion
• The android.depth.depthIsExclusive entry is listed by this device.
• A LIMITED camera with only the DEPTH_OUTPUT capability does not have to support normal YUV_420_888, 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 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.

Constant Value: 8 (0x00000008)

REQUEST_AVAILABLE_CAPABILITIES_MANUAL_POST_PROCESSING

int REQUEST_AVAILABLE_CAPABILITIES_MANUAL_POST_PROCESSING

The camera device post-processing stages can be manually controlled. The camera device supports basic manual control of the image post-processing stages. This means the following controls are guaranteed to be supported:

• Manual tonemap control

  • android.tonemap.curve
  • android.tonemap.mode
  • android.tonemap.maxCurvePoints
  • android.tonemap.gamma
  • android.tonemap.presetCurve

• Manual white balance control

  • android.colorCorrection.transform
  • android.colorCorrection.gains
• Manual lens shading map control
  • android.shading.mode
  • android.statistics.lensShadingMapMode
  • android.statistics.lensShadingMap
  • android.lens.info.shadingMapSize
• Manual aberration correction control (if aberration correction is supported)
  • android.colorCorrection.aberrationMode
  • android.colorCorrection.availableAberrationModes
• Auto white balance lock
  • android.control.awbLock

If auto white balance is enabled, then the camera device will accurately report the values applied by AWB in the result.

A given camera device may also support additional post-processing controls, but this capability only covers the above list of controls.

Constant Value: 2 (0x00000002)

REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR

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
  • android.sensor.frameDuration
  • android.sensor.info.maxFrameDuration
• Manual exposure control
  • android.sensor.exposureTime
  • android.sensor.info.exposureTimeRange
• Manual sensitivity control
  • android.sensor.sensitivity
  • android.sensor.info.sensitivityRange
• Manual lens control (if the lens is adjustable)
  • android.lens.*
• Manual flash control (if a flash unit is present)
  • android.flash.*
• Manual black level locking
  • android.blackLevel.lock
• Auto exposure lock
  • android.control.aeLock

If any of the above 3A algorithms are enabled, then the camera device will accurately report the values applied by 3A in the result.

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.

Constant Value: 1 (0x00000001)

REQUEST_AVAILABLE_CAPABILITIES_PRIVATE_REPROCESSING

int REQUEST_AVAILABLE_CAPABILITIES_PRIVATE_REPROCESSING

The camera device supports the Zero Shutter Lag reprocessing use case.

• One input stream is supported, that is, android.request.maxNumInputStreams == 1.
• PRIVATE is supported as an output/input format, that is, PRIVATE is included in the lists of formats returned by getInputFormats() and getOutputFormats().
• getValidOutputFormatsForInput(int) returns non empty int[] for each supported input format returned by getInputFormats().
• Each size returned by getInputSizes(ImageFormat.PRIVATE) is also included in getOutputSizes(ImageFormat.PRIVATE)
• Using PRIVATE does not cause a frame rate drop relative to the sensor's maximum capture rate (at that resolution).
• PRIVATE will be reprocessable into both YUV_420_888 and JPEG formats.
• The maximum available resolution for PRIVATE streams (both input/output) will match the maximum available resolution of JPEG streams.
• Static metadata android.reprocess.maxCaptureStall.
• Only below controls are effective for reprocessing requests and will be present in capture results, other controls in reprocess requests will be ignored by the camera device.
  • android.jpeg.*
  • android.noiseReduction.mode
  • android.edge.mode
• android.noiseReduction.availableNoiseReductionModes and android.edge.availableEdgeModes will both list ZERO_SHUTTER_LAG as a supported mode.

Constant Value: 4 (0x00000004)

REQUEST_AVAILABLE_CAPABILITIES_RAW

int REQUEST_AVAILABLE_CAPABILITIES_RAW

The camera device supports outputting RAW buffers and metadata for interpreting them.

Devices supporting the RAW capability allow both for saving DNG files, and for direct application processing of raw sensor images.

• RAW_SENSOR is supported as an output format.
• The maximum available resolution for RAW_SENSOR streams will match either the value in android.sensor.info.pixelArraySize or android.sensor.info.preCorrectionActiveArraySize.
• All DNG-related optional metadata entries are provided by the camera device.

Constant Value: 3 (0x00000003)

REQUEST_AVAILABLE_CAPABILITIES_READ_SENSOR_SETTINGS

int REQUEST_AVAILABLE_CAPABILITIES_READ_SENSOR_SETTINGS

The camera device supports accurately reporting the sensor settings for many of the sensor controls while the built-in 3A algorithm is running. This allows reporting of sensor settings even when these settings cannot be manually changed.

The values reported for the following controls are guaranteed to be available in the CaptureResult, including when 3A is enabled:

• Exposure control
  • android.sensor.exposureTime
• Sensitivity control
  • android.sensor.sensitivity
• Lens controls (if the lens is adjustable)
  • android.lens.focusDistance
  • android.lens.aperture

REQUEST_AVAILABLE_CAPABILITIES_YUV_REPROCESSING

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.
• YUV_420_888 is supported as an output/input format, that is, YUV_420_888 is included in the lists of formats returned by getInputFormats() and getOutputFormats().
• getValidOutputFormatsForInput(int) returns non-empty int[] for each supported input format returned by getInputFormats().
• Each size returned by getInputSizes(YUV_420_888) is also included in getOutputSizes(YUV_420_888)
• Using YUV_420_888 does not cause a frame rate drop relative to the sensor's maximum capture rate (at that resolution).
• YUV_420_888 will be reprocessable into both YUV_420_888 and JPEG formats.
• The maximum available resolution for YUV_420_888 streams (both input/output) will match the maximum available resolution of JPEG streams.
• Static metadata android.reprocess.maxCaptureStall.
• Only the below controls are effective for reprocessing requests and will be present in capture results. The reprocess requests are from the original capture results that are associated with the intermediate YUV_420_888 output buffers. All other controls in the reprocess requests will be ignored by the camera device.
  • android.jpeg.*
  • android.noiseReduction.mode
  • android.edge.mode
  • android.reprocess.effectiveExposureFactor
• android.noiseReduction.availableNoiseReductionModes and android.edge.availableEdgeModes will both list ZERO_SHUTTER_LAG as a supported mode.

SENSOR_TEST_PATTERN_MODE_COLOR_BARS

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.

Constant Value: 2 (0x00000002)

SENSOR_TEST_PATTERN_MODE_COLOR_BARS_FADE_TO_GRAY

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

int SENSOR_TEST_PATTERN_MODE_CUSTOM1

Constant Value: 256 (0x00000100)

SENSOR_TEST_PATTERN_MODE_OFF

int SENSOR_TEST_PATTERN_MODE_OFF

This is the default if the key is not set.

Constant Value: 0 (0x00000000)

SENSOR_TEST_PATTERN_MODE_PN9

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.

Constant Value: 4 (0x00000004)

SENSOR_TEST_PATTERN_MODE_SOLID_COLOR

int SENSOR_TEST_PATTERN_MODE_SOLID_COLOR

Each pixel in [R, G_even, G_odd, B] is replaced by its respective color channel provided in android.sensor.testPatternData.

For example:

android.testPatternData = [0, 0xFFFFFFFF, 0xFFFFFFFF, 0]
 

All green pixels are 100% green. All red/blue pixels are black.

android.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.
