Abstract

A multi-purpose or universal image display system, in which information obtained by scanning an information carrier with an image scan/display device may be displayed on the same device and also on other display devices, and also the image information obtained by the afore-mentioned scanning and video signals from other video signal generators may be displayed either selectively or as multiple display on the afore-said scan/display device.

Claims

1. An image display system comprising a scan/display device capable of scanning with a flying spot, a picture information carrier scanned by the flying spot of said scan/display device, a photoelectric transducer for converting light modified by said picture information carrier into a corresponding electric signal, means, responsive to the electric signal produced from said photoelectric transducer, for amplifying said electric signal and feeding back positively an output signal corresponding to the amplified electric signal, said means for amplifying including a stabilizing device for limiting the output signal at a predetermined level, and means for leading the output signal produced from said amplifying means and video signals from video signal generators either simultaneously or selectively to said scan/display device.

2. An image display system according to claim 1, which includes means for coupling the output signal produced from said amplifying means and the video signals from said video signal generators simultaneously to said scan/display device for multiple display.

3. An image display system according to claim 1, which includes means for causing the display of the output signal produced from said amplifying means and video signals from said the video signal generators either simultaneously or selectively on said scan/display device.

4. An image display system according to claim 1, which includes means for leading the output signal produced from said amplifying means to other display means than said scan/display device including a television receiver and a projector.

5. An image display system according to claim 1, which includes means for leading the output signal produced from said amplifying means to a means for obtaining a hard copy of said output signal.

6. An image display system according to claim 1, which includes means for selectively leading the output signal produced from said amplifying means to a memory.

7. An image display system according to claim 1, wherein said scaN/display device comprises a cathode-ray chromic tube.
