摘要：
There is provided a video processing device capable of reducing the influence of a disturbance of an input vertical synchronization signal. When the synchronization signal detecting unit detects an input of the input-side vertical synchronization signal at a predetermined cycle, the synchronization signal control unit outputs the input-side vertical synchronization signal, which has been input, as an output-side vertical synchronization signal, and, when the synchronization signal detecting unit detects an input of a next input-side vertical synchronization signal before the predetermined cycle elapses after the output of the output-side vertical synchronization signal, a next input-side vertical synchronization signal input before the predetermined cycle elapses is not output as a next output-side vertical synchronization signal, and an input-side vertical synchronization signal input further next is output as the next output-side vertical synchronization signal.
