Abstract

PURPOSE:To obtain a picture screen of good quality by detecting a vertical synchronizing signal stably by performing amplitude separation and frequency separation after processing an input video signal so that its vertical synchronizing pulse part and equalized pulse parts before and after it will increase in amplitude. CONSTITUTION:Television video signal input (a) is led to one input of adding circuit 3, whose output signal is delayed by delay circuit 5 with delay time a half as much as one horizontal period of the video signal and the delay output is led to the other input of adding circuit 3. Thus, an addition output signal is generated which has its amplitude-increased vertical synchronizing pulse part in the input video signal and equalized pulse parts before and after it and after this amplitude increase (b) is securely amplitude-separated, a vertical synchronizing signal is detected by frequency separation.
