PROBLEM TO BE SOLVED: To prevent a tone jump from occurring in not only an intensity direction but also a saturation direction as well as a hue direction while removing a base color, a show-through effect or the like. Ž

SOLUTION: When input image data in which colors of a plurality of pixels are predetermined are input from a scanner portion 20 and the input image data are converted and output image data for displaying output colors in a printer 40 are obtained, the colors each of which intensity exceeds a predetermined threshold value L*Tare converted into L=100 data so that the intensity smoothly changes in an intensity region having the threshold value L*Tor less. The saturation of the color is converted into 0 if the color having L=100 with respect to the converted color is in not only the predetermined saturation region of L*a*b*space but also the predetermined hue angle region.
