Abstract

PURPOSE:To elevate the definition of a picture at the time of varying speed reproduction through the aid of a field memory without necessitating to perform complicated phase adjustment by switching a signal to the signal from the field memory at the point of time when the synchronizing signal of a reproduced video signal from a head is detected. CONSTITUTION:The signal from a terminal 11 is led to the input terminal P of a selector switch 12, and at the same time, it is written in the DRAM 15 of one field portion through an A/D converter 13 and a serial/parallel converter 14. When a read out video signal from the DRAM 15 is made to follow continuously the reproduced video signal from the head, an address based on an address counter 20 is fixed at the point of time of the generation of a horizontal synchronizing signal of the read out video signal, and after waiting the time when the horizontal synchronizing signal is detected in the reproduced video signal by a synchronizing separation circuit 26, the fixing of the address is released, and the reproduced video signal is switched to the signal from the DRAM 15.
