Abstract
An image processing system,is arranged to produce data representing a combined image from foreground data F representing a foreground subject in front of a chroma backing and background data B representing a background image. The foreground data is processed and color corrected to produce first and second processed foreground data which is combined in a combiner,under the control of a first key K,. The background data is processed using a second key K,to “cut” a “hole” in the background image. The processed background data and the combined foreground data are added together in an adder,A third key K,is used to remove unwanted data from the added foreground and background data and to combine the resulting data with the processed background data in a combiner
