Abstract
A display synchronization signal generation apparatus and method, which make it possible to display a stable image irrespective of changes of horizontal and vertical frequencies of a received analog video signal in an analog video signal receiver. The display synchronization signal generation apparatus includes a detection unit, a change amount conversion unit, and a vertical synchronization signal generation unit. The detection unit detects an amount of change in a vertical period of an input video signal by comparing current and previous vertical periods of the input video signal. The change amount conversion unit converts the detected amount of change into the amount of change in a vertical period of a video signal to be displayed, using the current vertical period and the total number of pixels per frame. The vertical synchronization signal generation unit generates a vertical synchronization signal of the video signal to be displayed.
