Abstract

PURPOSE:To improve economical efficiency by reducing the number of picture elements of the color difference signal to the half for the luminance signal and by constituting equally memory circuits for the luminance signal and the color difference signal. CONSTITUTION:Slave screen R-Y signal A and slave screen B-Y signal B of color signal processing circuit 34 are selected alternately by switching signal C and are stored in memory 414. Meanwhile, memory circuit output signal F read out by read clock signal E is written into FF circuits 53 and 54 which constitute a one-picture element memory. Only the R-Y signal is selected and written into FF circuit 53 at the timing of rise of clock signal G. Meanwhile, only the B-Y signal is selected and written into FF circuit 53 at the timing of rise of clock signal H. Thus, a continuous slave screen signal can be reproduced.
