Abstract
An electronic graphic system 1 processes image data defining color values of a multiplicity of pixels that together form an image. The system 1 comprises a processing unit 14 in which image data from an image store 2 is processed with other image data from a store 9. The processing is effected on a pixel-by-pixel basis depending on control data in a control store 15 and on a predetermined gamma factor defining a relationship between color values and corresponding light values. The processing unit 14 thereby produces processed color value data representing a manipulated version of the image in which the light content of pixels has been varied by the other image data depending on the control data and the gamma factor.
