		/**
		* A set of bit masks for specifying how the received preview frames are
		* handled before the previewCallback() call.
		*
		* The least significant 3 bits of an "int" value are used for this purpose:
		*
		* ..... 0 0 0
		* ^ ^ ^
		* \| \| \|---------> determine whether the callback is enabled or not
		* \| \|-----------> determine whether the callback is one-shot or not
		* \|-------------> determine whether the frame is copied out or not
		*
		* WARNING: When a frame is sent directly without copying, it is the frame
		* receiver's responsiblity to make sure that the frame data won't get
		* corrupted by subsequent preview frames filled by the camera. This flag is
		* recommended only when copying out data brings significant performance price
		* and the handling/processing of the received frame data is always faster than
		* the preview frame rate so that data corruption won't occur.
		*
		* For instance,
		* 1. 0x00 disables the callback. In this case, copy out and one shot bits
		* are ignored.
		* 2. 0x01 enables a callback without copying out the received frames. A
		* typical use case is the Camcorder application to avoid making costly
		* frame copies.
		* 3. 0x05 is enabling a callback with frame copied out repeatedly. A typical
		* use case is the Camera application.
		* 4. 0x07 is enabling a callback with frame copied out only once. A typical
		* use case is the Barcode scanner application.
