<P>PROBLEM TO BE SOLVED: To obtain a video display control apparatus capable of realizing a function of adjusting a video signal synchronized with a synchronization signal, at low cost. <P>SOLUTION: A horizontal position detector 35 receives a digital video signal 31a and a horizontal synchronization pulse 31b, and outputs a video delay control signal 35a and a horizontal synchronization delay control signal 35b corresponding to a shift amount between a timing of the digital video signal 31a synchronized with the horizontal synchronization pulse 31b and a timing of the digital video signal 31a that is actually inputted. A delay selection circuit 46 for a video signal and a delay selection circuit 47 for a synchronization signal select any one output of flip-flop circuits 36-40 and flip-flop circuits 41-45, respectively, based on the delay control signal 35a, and output the selected output as a horizontal position adjusted digital video signal 32a and a horizontal position adjusted horizontal synchronization pulse 32b, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
