Abstract

Multi-scene display system for simultaneously displaying a plurality of scenes on a display screen, divides each scene into a plurality of regions and stores the scenes by regions. When displaying plural scenes on the display screen, the screen is divided into a number of parts equal to the number of scenes to be displayed and only the central regions of each scene displayed in a respective part of the display screen.

Claims

1. A multi-scene display system, comprising:

means for receiving a video signal representing a plurality of scenes;

means for storing each of said scenes as a plurality of regions; and

means for simultaneously displaying only selected regions of said plurality of scenes.

2. A multi-scene display system as claimed in claim 1, wherein said means for simultaneously displaying includes means for simultaneously displaying only the central regions of said plurality of scenes.

3. A multi-scene display system as claimed in claim 1, further includes;

a video recording medium;

a recording/reproducing means for recording all the regions of said plurality of scenes on said video recording medium and for reproducing the recorded regions; and

controller means for selecting for display only central regions of a plurality of said reproduced regions corresponding to said plurality of scenes; and

said means for simultaneously displaying includes display means for simultaneously displaying said selected central regions of a plurality of said regions.

4. A multi-scene display system as claimed in claim 3, wherein;

said video signal receiving means includes a video chromatic circuit means for producing, in response to said video signal, luminance and color difference signals representing the plurality of scenes conveyed by the video signal, and analog to digital conversion means, responsive to the output of said video chromatic circuit means, for producing digital signals representative of said plurality of scenes to be applied to said storing means;

said multi-scene display system further including switch means for selectively applying to said storing means signals representing at least one scene or selected scene regions reproduced from said video recording medium.

5. A multi-scene display system as claimed in claim 4, wherein said controller means includes means for placing said switch means in a selected state.

6. A multi-scene display system as claimed in claim 5, wherein said display means includes digital to analog conversion means, coupled to said storing means for converting digital signals representing regions read out of said storing means into analog luminance and color difference signals, a matrix circuit receiving the outputs of the digital to analog conversion means, and a display coupled to the matrix circuit.

7. A multi-scene display system as claimed in claim 6, wherein said video recording medium stores together the selected central regions of said plurality of regions corresponding to said plurality of scenes, whereby the together stored central regions can be reproduced quickly and rapidly displayed simultaneously.

8. A multi-scene display system comprising:

a video chromatic circuit means for receiving an analog video signal and outputting a luminance signal and color difference signals corresponding to the picture information contained in the analog video signal, said picture information representing a plurality of scenes;

an analog to digital conversion means for converting said luminance and color difference signals to digital signals representing said picture information;

memory means for storing the picture information corresponding to a scene in a plurality of defined regions;

controller means for controlling the writing into and reading out of said memory means;

a video recording medium for storing said plurality of scenes;

a recording/reproducing means responsive to said controller for recording the picture information of defined regions of each of said plurality of scenes read from said memory means on said video recording medium;

a video display means; and

means, responsive to said controller and coupled to said memory means, for simultaneously displaying on said video display means only selected regions of said plurality of scenes.

9. A multi-scene display system as claimed in claim 8, wherein said means for simultaneously displaying displays only the central regions of said plurality of scenes.
