A skin-color-area detector generates a skin- color-area signal from an input video signal. An average luminance level detector generates an average luminance level signal from a luminance signal. These signals are transmitted to a skin-color-corrector to generate skin- color-correction signals. At a saturation controller and at a luminance signal corrector which each receive the skin color corrections signals, skin-color is optimumly corrected. Thereby reproduction quality of skin-color signals in video signals is enhanced.
