ABSTRACT:
An image processing method which converts R, G and B multivalued image signals into color signals corresponding to coloring materials used for an image forming means, comprising the step of converting an achromatic color used to control a skin color and at predetermined brightness into a predetermined value. Thus, the skin color difficult to be satisfactorily reproduced can be easily converted into a desirable color by controlling the achromatic color. Moreover, the skin color on the various media can be approximately unified by setting the achromatic color having high brightness to be approximately the same even on the plural media respectively having different paper colors.
