ABSTRACT:
A matrix circuit for separating a color signal of a video camera into color-difference signals comprises an adder circuit for combining R, G, B signals into composite color signals R-G and B-G, time division circuit for subjecting the composite color signals R-G and B-G to time division process according to externally input clock pulses, and demultiplexer for demultiplexing the output of the time division circuit according to externally input clock pulses to produce two color difference signals R-Y and B-Y.
