ABSTRACT:
A chrominance signal constituting a color image is modulated to generate a modulated chrominance signal. A phase difference between this modulated chrominance signal and a signal corresponding to a particular color is detected. The saturation of the chrominance signal where the phase difference is small is enhanced, thereby making it possible to readily discern a portion of a particular hue from a surrounding portion having a hue different from that hue.
