PURPOSE:To enable to reproduce a superior still picture with simple constitution by generating a clock signal that is synchronized with a synchronizing signal for re-writing to a memory and reading out information stored at the memory by this clock signal. CONSTITUTION:When the still picture is reproduced, a switch 23 is switched to (b) side and a compound signal that is added to an amplifier 2 is supplied to an LPF3, a synchronization separation circuit 10 and a BPF11. At the LPF3, an unnecessary frequency component of the signal is eliminated and the signal is converted to a digital signal at an A/D converter 4 and is written to a memory 5 by share of one field in order. So that a jitter component is included in the signal written at the memory 5, a synchronizing signal generating circuit 21 is operated and dummy horizontal and vertical synchronizing signals are generated and these dummy signals are to be synchronized with the synchronizing signal that is used for the re-writing of the memory 5. As a result, the superior reproduction of the still picture can be realized.
