Attributes

Remarks

Property getter documentation:

Gets the state of the auto-white balance lock. Applications should check #isAutoWhiteBalanceLockSupported before using this method. See #setAutoWhiteBalanceLock for details about the lock.

Java documentation for android.hardware.Camera.Parameters.getAutoWhiteBalanceLock().

Property setter documentation:

Sets the auto-white balance lock state. Applications should check #isAutoWhiteBalanceLockSupported before using this method.

If set to true, the camera auto-white balance routine will immediately pause until the lock is set to false.

If auto-white balance is already locked, setting this to true again has no effect (the driver will not recalculate white balance values).

Stopping preview with #stopPreview(), or triggering still image capture with #takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback), will not change the the lock.

Changing the white balance mode with #setWhiteBalance will release the auto-white balance lock if it is set.

Exposure compensation, AE lock, and AWB lock can be used to capture an exposure-bracketed burst of images, for example. Auto-white balance state, including the lock state, will not be maintained after camera #release() is called. Locking auto-white balance after #open() but before the first call to #startPreview() will not allow the auto-white balance routine to run at all, and may result in severely incorrect color in captured images.
