同期信号処理回路。A gate circuit that is supplied with a synchronization signal in which a variation in the pulse width of a cutting pulse inserted into the vertical synchronization signal is expected, and extracts equalization pulses inserted before and after the vertical synchronization signal in the synchronization signal; and this gate circuit. A signal processing circuit that is supplied with the equalization pulse extracted by the controller, forms a pulse that lasts during the period from the pre-inserted equalization pulse to the post-inserted equalization pulse, and uses this pulse as a pseudo vertical synchronization signal. Synchronous signal processing circuit.
