Abstract
PURPOSE:To reduce the deterioration in various pictures due to incomplete YC separation by applying the processing of YC separation at a 3-dimensional frequency region. CONSTITUTION:A 3-dimensional YC separation circuit 1 extracts separately only the region corresponding to a chrominance signal C and a YH' signal as a C signal and extracts separately other region as a Y signal component. The separated C signal is subjected to polarity inversion processing at a polarity inversion circuit 2 and added to the separated Y signal by an adder circuit 3 to constitute a signal of the composite form whose polarity is inverted. Then a switch circuit 4 uses a control signal to select both alternately in, e.g., a frame period to generate a normal NTSC television signal. Thus, the YC separation processing without deterioration is applied to the existing television signal.
