Video signal processing apparatus configured to display a video having a resolution higher than full HD, video display apparatus, and electronic device

摘要

The time necessary for specifying an improper video signal is significantly reduced. An input signal determination circuit and a signal distribution circuit are included, the input signal determination circuit determining, for video signals to be input to a synchronization circuit, whether or not each of the video signals satisfies a display reference for performing video display in a division display area corresponding to the video signal, the signal distribution circuit distributing, for another proper video signal for a video signal determined by the input signal determination circuit to be a video signal that does not satisfy the display reference for performing video display.
