Abstract

A color hard copy of a picture displayed on, for example, a screen of a color television set is obtained by a signal converter in which an inclination of brightness with respect to the saturation of a color of the hard copy is modified by a signal converting circuit so as to be in accord with an inclination of brightness with respect to the saturation of the displayed color picture, a signal level of a signal regarding the specific color designated by a color setter is changed, and the color development density of the specific color element designated by a dye amount setter is also changed, whereby a color hard copy in which the specific color is maximumly corrected can be obtained.
