1. A system for divisionally displaying four images on a monitor screen comprising:

  • a microcomputer;

    first to fourth video signal processing sections for separating camera video signals from four cameras into a luminance signal and color difference signals, respectively, for latching the signals after converting same into digital signals, and for outputting the digital signals during first to fourth divisional region scanning periods of the monitor under control of the microcomputer;

    a synchronous generator for producing synchronous signals and color burst signals;

    an ON-screen generator for producing an ON-screen signal by being synchronized with the synchronous signals of the synchronous generator under the control of the microcomputer;

    digital/analog converters for converting the output signals of the first to fourth video signal processing sections and the output signal of the ON-screen generator into analog signals; and

    an encoder for synthesizing a synthetic video signal from the output signals of the digital/analog converters with the synchronous signals of the synchronous generator and the color burst signals and then outputting said synthetic video signal.
