Abstract
PURPOSE:To change color saturation according to the level of a video signal and to suppress a color noise by reducing a color gain at the time of a dark screen by superimposing the video signal on a voltage for controlling the color saturation. CONSTITUTION:To a color saturation control terminal 1, the direct voltage for controlling the color saturation optimally adjusted is given, and the voltage is impressed to a diode 6 and a resistance 8. On the other hand, the video signal is inputted through a transistor 3 to a condenser 5 for peak clamping. To the base of a transistor 9, the color saturation control voltage is obtained on which the peak-clamped video signal is superimposed.
