Abstract

A color correcting method of a color printer is provided. Input image data expressed by lightness (or brightness), saturation, and hue is compared with a color expression range of a color printer similarly expressed by lightness, saturation, and hue. The input image data is used without change as output data with respect to that input image data which is found to overlap the color expression range of the color printer as a result of the comparison. Output data is formed by changing the lightness of the input image data when the data is converted to a point on the outer edge of the color expression range of the color printer with respect to any portion of the input image data which does not overlap with the color expression range of the color printer.
