Enum Values

public static final Config.UpdateMode BLOCKING

BLOCKING

public static final Config.UpdateMode BLOCKING

update() will normally wait until a new camera image is available. On most devices the camera is configured to capture 30 frames per second.

Note: If the camera image does not arrive by the built-in timeout (currently 66ms), then update() will instead return the most recent Frame object.

public static final Config.UpdateMode LATEST_CAMERA_IMAGE

LATEST_CAMERA_IMAGE

public static final Config.UpdateMode LATEST_CAMERA_IMAGE

update() will return immediately without blocking. If no new camera image is available, then update() will return the most recent Frame object.
