Abstract
An apparatus for providing a foreground frame to be composited with a background frame in a chroma-keying arrangement, each of the foreground frame and the background frame comprising one or more regions that together form the respective frame. A detection module determines whether each frame region has a predetermined colour value and generates and stores chroma keying information based on the determination. Control circuitry then controls image processing to be performed on the region according to the stored chroma keying information.
