ABSTRACT:
A color image processing device in which color signals representing a color of individual picture elements are input as addresses to a first semiconductor device so that correction data for correcting an target picture element are successively outputted for every separated color. A second semiconductor device is used to hold correction data for a particular color so that it can be simultaneously outputted to a logic circuit with additional correction data from the first semiconductor device for another color. The logic circuit combines the correction data from the first and second semiconductor devices with signals from the target picture element and outputs a corrected signal representing a corrected color for the target picture element.
