PCT No. PCT/JP82/00418 Sec. 371 Date Jun. 22, 1983 Sec. 102(e) Date Jun. 22, 1983 PCT Filed Oct. 21, 1982 PCT Pub. No. WO83/01554 PCT Pub. Date Apr. 28, 1983.In accordance with a carrier chrominance signal separating circuit of this invention, a mixed signal containing a carrier chrominance signal C is supplied to a delay circuit (6) and delayed one horizontal period. This delayed signal and an original color video signal are supplied to a subtracting circuit (14) and the subtracted output therefrom and the original color video signal are supplied to an amplitude correlating circuit (9) from which the carrier chrominance signal is generated. Thus, even if the carrier chrominance signal C includes signal portions having no vertical correlation therebetween, the carrier chrominance signal will never be lost or attenuated.
