Abstract
Timing of internally generated horizontal synchronization signal and vertical synchronization signal is shifted. An internal clock is synchronized with a horizontal synchronization signal separated in a synchronization separation circuit, an H reset signal is generated based thereon in an H countdown circuit, and a horizontal synchronization signal is generated based thereon. A vertical synchronization signal separated in the synchronization separation circuitis normalized by a 2×FH signal obtained in the H countdown circuit, and based on an obtained V reset signal, a vertical synchronization signal is obtained in a VS output circuit. Here, the VS output circuitinternally has a delay circuit, and the timing of a vertical synchronization signal VS to be output is shifted from that of a horizontal synchronization signal HS.
