ABSTRACT:
A synchronization signal generation circuit includes: a synchronization signal generation section for generating a first vertical synchronization signal and a first horizontal synchronization signal based on an externally-supplied second vertical synchronization signal; and a detection section for detecting the second vertical synchronization signal, wherein when the second vertical synchronization signal is detected by the detection section for the first time, the first vertical synchronization signal is not output by the synchronization signal generation section, and when the second vertical synchronization signal is detected by the detection section for the next time at a predetermined timing, the first vertical synchronization signal is output by the synchronization signal generation section.
