Abstract

PURPOSE:To enable to reduce a delay time of the delay circuit, and to bring the cost down by processing a color compounding signal with a frequency conversion means, a filter means, a delay circuit, addition and subtraction means, etc. CONSTITUTION:A color compounding signal which has come into the input terminal 1 is delayed by the delay circuit 16, and after that, it is provided to the adder 17, and is added to a chrominance signal. A color multiple signal which has been obtained in this way is delayed by the delay circuit 18, and after that, it is provided to the subtractor 19, and is subtracted from a chrominance signal outputted from the frequency transducer 7. A standard NTSC color video signal is output to the output terminal 15 from the subtractor 19.
