Abstract:
A process in adjusting, according to a sequence of synchronous pulses, the timing of the active part of a video signal for displaying, comprising the steps of:(1) detecting if the trailing end of the active part of said video signal lags the synchronous pulse which is next to the leading end of the active part of said video signal;(2) in case the trailing end of the active part of said video signal lags the synchronous pulse which is next to the leading end of the active part of said video signal, advancing the active part of said video signal by an adjustment step value;(3) repeating step (1) and step (2) until the trailing end of the active part of said video signal leads, by a leading time period, the synchronous pulse which is next to the leading end of the active part of said video signal, said leading time period has minimum length of zero.
