ABSTRACT:
A video signal processing apparatus has an A/D converter for converting a video signal to a first digitized video signal, a timing pulse generator for generating a plurality of timing pulses, a multiplexer for selecting an output signal, a serial video processor for storing the first digitized video signal and outputting a digitized video signal in accordance with the selected output signal of the multiplexer, and D/A converter for converting the digitized video signal to a video signal. A panoramic picture can be obtained so that a display cutting problem in a zoom display and a lack of realistic display in a wide-aspect display can be eliminated.
