Abstract
An apparatus and method for color image adjustment which ensure proper saturation adjustment by a simple process. Color image data for three primary colors are adjusted so that the sum of the color image data for the three primary colors is kept unchanged before and after the adjustment. Thus, the saturation adjustment can be achieved without a change in the brightness of an image.
