Abstract
An electronic graphic system,processes image data defining color values of a multiplicity of pixels that together form an image. The system,comprises a processing unit,in which image data from an image store,is processed with other image data from a store,The processing is effected on a pixel-by-pixel basis depending on control data in a control store,and on a predetermined gamma factor defining a relationship between color values and corresponding light values. The processing unit,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.
