ABSTRACT:
In normal reproduction, a switch circuit (11) is set to select an output signal of an A/D converter (1). Consequently, a movement adaptation type YC separating circuit is formed, whereby a luminance signal and a chrominance signal are separated. When a control signal is outputted from a control signal generating circuit (12) in response to an instruction of still picture reproduction, the switch circuit (11) selects an output signal of the last output terminal of delay means formed by line memory (2) or frame memory (3) and inputs the selected signal to the first input terminal of the delay means. As a result, in still picture reproduction, a circulating circuit where the inputted composite video signal circulates in the delay means is formed and a luminance signal and a chrominance signal are separated based on a plurality of composite video signals having different delay times obtained from the circulating circuit. Thus, the delay means provided in the movement adaptation type YC separating circuit is used also for processing of still picture reproduction.
