Abstract:
An image processing system in which:foreground image data representing pixels that together form an image of a foreground subject in front of a chroma backing is processed to produce first processed foreground data representing pixels that together form a colour corrected image of the foreground subject in front of the chroma backing and second processed foreground data representing pixels that together form an image of the foreground subject in front of a null backing;the first and second processed foreground data is combined, under the control of first control data representing pixels that together form a first control image, to produce combined foreground data representing pixels that together form an image of the colour corrected foreground subject in front of the null backing;background image data representing pixels that together form an image of a background is processed, under the control of second control data representing pixels that together form a second control image, to produce processed background image data representing pixels that together form an image of the background with one or more null portions at areas corresponding in position to that of the foreground subject in the image represented by the foreground image data; andthe combined foreground data and the processed background data are added together to produce data representing pixels that together form an image of the colour corrected foreground subject in front of the background.
