PURPOSE:To execute separation between a luminance signal and a chrominance signal and a linear sequence compensation of the chrominance signal in a relatively small circuit scale by exeuting the chrominance signal compensation and the time adjustment of the luminance signal in the state that the luminance signal and the chrominance signal are time division multiplied. CONSTITUTION:A linear sequence multiple color television signal which is added to an input terminal 11 is supplied sequentially to one-line delay circuits 18 and 19. The output of the one-line delay circuit 19 is supplied to a 1/2 multiplier 22, and added by an adder 23 together with the input signal which is added to a 1/2 multiplier 21. A chrominance signal I which is linear-sequence-compensation- processed is obtained from the adder 23 linear-sequentially, the signal which is not compensation-processed is obtained from the delay circuit 18, and the signal is given to switching circuits 32 and 33. By switching the switching circuits 32 and 33 by the line synchronizing, respective outputs of the switching circuits 32 and 33 are separated to two kinds of chrominance signals C1, C1' and C2, C2', and the time base is expanded and outputted by respective expanding circuits 16 and 17. |
