る合成カラービデオ信号発生装置。a signal generation circuit that generates a signal that does not need to have a synchronization relationship with the input video signal; a synchronization signal separation circuit that separates a horizontal synchronization signal and a vertical synchronization signal from the human video signal; a switching pulse forming circuit that forms a switching pulse based on a horizontal synchronizing signal and a vertical synchronizing signal, and switching between the signal from the signal generation circuit and the human video signal using the switching pulse to output a composite color video signal. In the composite color video signal generating device, the pulse width of the switching pulse is gradually changed from a predetermined point in time, so that the combination ratio of the two signals is changed.
