Abstract
PURPOSE: To make it possible to obtain a sharp regenerative screen with a blur of color removed by selecting either one of correction signals generated by two color correction circuits by a switching circuit controlled by two control signals.
CONSTITUTION: Switching circuit 19 selects either one of correction signals generated independently by color correction circuits 10 and 20 and superposes it upon a color difference signal. In this case the 1st and 2nd control signals are generated and supplied to the control circuit 40 since circuit 40 selects correction signals; the 1st control signal is generated on the basis of the differentiation output of the low-band signal of luminance signal Y, and the 2nd control signal is on the basis of the integral output of the high-band signal of luminance signal Y and the differentiation output of a signal with a band narrower than that of the low-band signal. Consequently, a sharp regenerative screen can be obtained with a blur of color removed.
