Abstract

PURPOSE:To make it possible to separate the luminance signal and the chroma signal correctly even in case of the video signal having jitter, by varying the delay time of a delay element. CONSTITUTION:In separating circuit 2, delay element 3 is constituted as a variable one; and if the CCD and so on are used, the delay time can be controlled by the frequency of clock pulses, and the delay time of this delay element 3 is controlled by the phase comparison output between the synchronizing signal separated from the video signal and the synchronizing signal separated from the video signal output from this delay element 3.
