ABSTRACT:
The hue of a color image is controlled by a detector which monitors the luminance signal level to produce a gain control signal when it exceeds a predetermined level to effect reduction in the relative proportion of the red content in a whitish area in the color image without sacrifice to adversely affect the faithful reproduction of flesh tones. The detector may be arranged to monitor the output level of red primary color so as to effect control in the amount of the red color output so that redish cast in the color image is effectively suppressed without sacrifice in the reproduction of flesh tones.
