ABSTRACT:
A synchronizing pulse signal generation device separates horizontal and vertical synchronizing signals from a video signal; generates a clock signal which is phase locked relative to the phase of the horizontal synchronizing signal; and generates, by using the clock signal, a synchronizing pulse signal which is phase locked relative to the vertical and horizontal synchronizing signals.
