Abstract

PURPOSE:To reproduce a satisfactory color picture by controlling a specific color part of a color picture signal by a luminance level, clipping its color level, and simultaneously controlling the luminance level so as to correspond to a hue to be reproduced. CONSTITUTION:An M signal from the M signal input terminal 1 is provided to TR8 through the contrast control circuit 2 and the bright control circuit 3 as an output from the emitter of the transistor TR4. Also, an index signal and a chrominance carrier signal which have been obtained in case of scanning the fluorescent surface of the image receiving tube 9, and an index color signal having the information are provided to TR10 from the index color signal application terminal 10. Furthermore, a blanking pulse is applied to the blanking pulse application terminal 16, and a signal waveform which has mixed a mean DC component of the luminance component and a color signal component is input to the cathode 15 of the image receiving tube 9. And, the signal waveform is controlled and clipped at a luminance level by the color signal and the chrominance subcarrier which have been provided to the color signal input terminal 70 and the chrominance subcarrier signal input terminal 71, so that a satisfactory color picture can be reproduced.
