Java android.hardware.camera2 CameraMetadata fields, constructors, methods, implement or subclass

The camera device faces the same direction as the device's screen.

The camera device faces the opposite direction as the device's screen.

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.

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

Basic automatic focus mode.

In this mode, the lens does not move unless the autofocus trigger action is called.

The trigger is idle.

Autofocus will trigger now.

Autofocus will return to its initial state, and cancel any currently active trigger.

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 CaptureRequest#CONTROL_CAPTURE_INTENT 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.

Use settings for each individual 3A routine.

Manual control of capture parameters is disabled.

Do not fire the flash for this capture.

Return all face metadata.

In this mode, face rectangles, scores, landmarks, and face IDs are all valid.

One or several of the lens parameters ( CaptureRequest#LENS_FOCAL_LENGTH android.lens.focalLength , CaptureRequest#LENS_FOCUS_DISTANCE android.lens.focusDistance , CaptureRequest#LENS_FILTER_DENSITY android.lens.filterDensity or CaptureRequest#LENS_APERTURE android.lens.aperture ) is currently changing.
