Apparatus and method of generating synchronizing pulse

摘要

Synchronizing pulses are generated based on horizontal synchronizing signals carried by an input television (TV) signal. A first pulse is generated at the same timing as each of the synchronizing signals. A control pulse is generated in response to the first pulse. The generation of the first pulse is controlled so that it depends on a width of the control pulse. The first pulse is output, in response to the first pulse, as each of the synchronizing pulses at the same timing as the horizontal synchronizing signals. The control pulse is shifted for a period of time by which one of the horizontal synchronizing signals has been shifted. One of the synchronizing pulses is thus shifted for the period of time. The synchronizing pulse corresponds to the shifted horizontal synchronizing signal. <IMAGE>
