Abstract

PURPOSE:To enjoy an abstract video image by switching an output being the result of video signal processing to a TV video signal and a primary color signal from a connector so as to extract the abstract video image. CONSTITUTION:An output signal of a video intermediate frequency amplifier circuit VIF 3 is outputted to a video signal processing circuit 5 and outputted to a synchronizing separator circuit 11 via connectors 4, 10. A horizontal synchronizing signal Hs and a vertical synchronizing signal Vs are obtained from the circuit 11 and outputted to sawtooth generating circuits 12, 13, from which a sawtooth wave is obtained. The obtained horizontal and vertical sawtooth wave signals are input to a pulse synthesis circuit 18 via voltage comparator circuits 14, 16 and an extraction signal Ys is obtained. An abstract video image is displayed on a CRT 8 by using the extraction signal Ys so as to switch the primary color signal outputted from the circuit 5 and the primary color signal given from the connector 10 by means of the signal switching circuit 6.
