置。[Claims for Utility Model Registration] In a video signal processing device that separates and processes a composite video signal into a composite synchronization signal VS and a video signal VI, a video signal storage unit 1 stores the video signal VI.
a pseudo synchronization signal generator 2 that generates a signal VS' that is the same as the composite synchronization signal VS; a comparator 3 that compares the field strength of the received radio wave with a reference value; and a comparator 3 that compares the field strength of the received radio wave with a reference value. a storage section input side switch section 4 which stops the input to the video signal storage section 1 by the comparator 3 when the voltage becomes low; and a storage section which selects and outputs the video signal VI' from the video signal storage section 1. A video signal processing device comprising an output side switch section 5 and a synchronization signal switching switch section 6 for selectively outputting the synchronization signal VS' from the pseudo synchronization signal generation section 2.
