ABSTRACT:
An image processor which improves the reproducibility of the color blue, includes an input device which inputs color image data, and a color correction device which performs color correction of the input color image data based on color correction parameters. An output device outputs the color corrected input image data to an image forming device that forms an image by using recording materials corresponding to a plurality of colors including magenta and cyan. The color correction device decreases the amount of magenta used for image formation, and uses the color correction parameters to suppress the elimination of gradation in a color zone formed by cyan.
