PURPOSE:To reproduce a color tone being approximate to a memory color of a viewer as to an intermediate color such as a skin color, etc., by means of a simple circuit configuration, and to improve inconvenience which is caused in other primary color information, by providing an automatic demodulation gain and phase controlling circuit on an output side of a color demodulating circuit of color television. CONSTITUTION:R-Y, G-Y and B-Y signal components are outputted to output terminals 7-9 of a color demodulating circuit 11, respectively, and the respective signal components are inputted to a video outputting circuit of the next stage. To an output terminal 9 of this circuit 11 is connected an automatic demodulation gain and phase controlling circuit 12. Between a connection point of this circuit 12 and the terminal 9, and reference voltage are connected resistances R6, R7, to a connection point of said resistances R6, R7 is connected the base of a transistor (TR) Q3, and the collector of this TRQ3 is connected to the base of TRQ1 which has been connected between the terminal 9 and a CRT13. Also, to the emitter of the TRQ1 is connected the emitter of a TRQ2 which inputs a luminance signal component to its base, and an intermediate color such as a skin color, etc. is reproduced irrespective of other primary color, by a simple circuit configuration. |
