Whether auto-white balance (AWB) is currently setting the color transform fields, and what its illumination target is.

This control is only effective if CaptureRequest.ControlMode is AUTO.

When set to the ON mode, the camera device's auto-white balance routine is enabled, overriding the application's selected CaptureRequest.ColorCorrectionTransform, CaptureRequest.ColorCorrectionGains and CaptureRequest.ColorCorrectionMode.

When set to the OFF mode, the camera device's auto-white balance routine is disabled. The application manually controls the white balance by CaptureRequest.ColorCorrectionTransform, CaptureRequest.ColorCorrectionGains and CaptureRequest.ColorCorrectionMode.

When set to any other modes, the camera device's auto-white balance routine is disabled. The camera device uses each particular illumination target for white balance adjustment. The application's values for CaptureRequest.ColorCorrectionTransform, CaptureRequest.ColorCorrectionGains and CaptureRequest.ColorCorrectionMode are ignored.

Possible values:

• CameraMetadata.CONTROL_AWB_MODE_OFF
• CameraMetadata.CONTROL_AWB_MODE_AUTO
• CameraMetadata.CONTROL_AWB_MODE_INCANDESCENT
