PURPOSE:To provide a wide mode without adding any means for turning on/off S-shaped correction to a horizontal deflecting system. CONSTITUTION:A luminance signal Y and color difference signals B-Y and R-Y are supplied to respective digital memories 16a, 16b and 16c. The write of these respective digital memories 16a, 16b and 16c is controlled by a sampling clock fCW of a write control circuit 18, and the read of the respective digital memories 16a, 16b and 16c is controlled by a sampling clock fCR of a read control circuit 19. Then, a clock oscillator 24 of the read control circuit 19 outputs the sampling clock fCR that frequency is modulated by a horizontal scanning block cycle based on the modulated voltage of a modulated voltage generator 31. |
