Abstract:
A picture signal processing apparatus comprising:first control signal generating means for receiving three prime color input signals and for generating a first control signal in accordance with a signal level of the one of the three received prime color input signals having the highest signal level; second control signal generating means for receiving the three prime color input signals and for generating a second control signal in accordance with the signal level of the one of said three received prime color input signals having the highest signal level; first saturation compression means for compressing only color saturation of color image signals represented by said three prime color input signals in response to said first control signal so that, in a state in which color hue and luminance of said color image signals are maintained, the signal level of the one of said three prime color signals having the highest signal level is at a predetermined signal level; and second saturation compression means for compressing only color saturation of the compressed color image signals, compressed in saturation by said first saturation compression means, in a state in which the luminance and the color hue are maintained, in response to said second control signal.
