ABSTRACT:
A color image processing system in which image data generated in other systems can be commonly used is disclosed. In the color image data processing system, an image processing unit processes color image data represented in a uniform color space system under illumination by a first light source, and the image data includes information relating to the first light source. An image output unit receives color image data represented in a uniform color space system under illumination by a second light source and produces color images according to the color image data. A correction control unit in the image processing unit judges whether or not the first light source coincides with the second light source. A correction formula calculating unit calculates a correction formula corresponding to the difference in characteristics between the first light source and the second light source. A light source difference correction unit corrects the color image data according to the correction formula.
