ABSTRACT:
A color image processing apparatus generates color image data, measures the quantity of the image data within a predetermined region of color space, obtains a representative color value for the image data within that region, and corrects the color image data based on the representative value and the measured quantity.
The number of image data which exist within a predetermined region on a (u,v), chromaticity diagram and which are among input color image data is counted. When the counted number is smaller than a predetermined value, the correcting operation is not executed. The difference between a predetermined coordinate point and a coordinate point at which the largest counted number of image data exist is obtained, and by the obtained distance either all the image data or the image data within the predetermined region are corrected.
