Abstract
An image processing system operates on first and second image data (V and Bg) to produce data defining a combined image. The first image data (V) represents a keyed image comprising a first object (F) keyed over a portion of a first background (B) in accordance with keying data (K). The second image data (Bg) represents a background. The system is arranged so that the second image data (Bg) is weighted by respective control data (.alpha.) related to said keying data (K) before being combined with the first image data (V). In another embodiment the first image data represents a second object independently keyed over the keyed image in accordance with second keying data and the control data is further related to the second keying data. In a further embodiment the first image data represents an image derived by cross fading between the first keyed image and a second keyed image.
