System for divisionally displaying plural images on a screen
First Claim
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.

Abstract
A system for divisionally displaying plural images on a monitor screen and capable of displaying video signals inputted from four monitoring cameras on one screen by dividing in four parts and of recording one signal out of the signals being displayed on one screen divided in four or video signals being directly inputted from video cameras. The system includes first to four video signal processing sections for processing four camera video signals, synchronous generator for producing synchronous signal and color burst signal, an ON-screen generator, digital/analog converters for converting the output signals of the video signal processing sections and the ON-screen generator, and an encoder for synthesizing the output signals of the digital/analog converters with the synchronous signals and color burst signal of the synchronous generator.
