Abstract

PURPOSE:To make it possible not to cause skewness and vibration in the vertical direction on the reproducing picture, by generating a pseudo vertical synchronous signal in accordance with the reproducing signal, and inserting it into the output signal. CONSTITUTION:A switching signal from the switching signal generating circuit 10 is provided to the bipolar differentiation circuit 19, and a differential signal obtained in this way is provided to the monostable multivibrator 23 after its waveform has been shaped by the waveform shaping circuit 21. An output of the monostable multivibrator 23 is provided to the pseudo vertical synchronous signal forming circuit 27, a pseudo vertical synchronous signal is provided to the inserting circuit 28, and a video signal which has inserted the pseudo vertical synchronous signal into the output terminal 29 is output.
