PROBLEM TO BE SOLVED: To enable to avoid the iteration of an interlaced imaging, an identical video image effectively even when the video signal in which synchronizing is not stabilized is processed by applying a video signal outputted from, for example, a home use video tape recorder. SOLUTION: The frequency of a read-out clock RCK is set variable so that the mean rate of the values of the difference value of a write address and a read-out address in a memory circuit 6 turns into a predetermined value.
