Abstract

PURPOSE:To obtain a stereoscopic TV which can in common be used with a usual TV, through the use of an electronic optical shutter, by selectively outputting a left and right limit video signal having a parallax at an interlace with an odd and an even number of fields, and shading off one of the video signal. CONSTITUTION:A left and right limit video signals with paprallax are picked up with TV cameras 2 and 3, and the discrimination with an odd and an even number fields of the video output is made at a field discrimination circuit 5 inputting a signal of a synchronizing signal generator 4. The output of the circuit 5 controls a multiplex switching circuit 6 and outputs the standard TV signal from the circuit 6. In this case, the focus of the camera 2 or 3 is shaded off and a TV signal from the circuit 6 is pictured on a monitor TV via a transmission medium 7. The picture of the receiver 8 is switched according to each left and right limit with a field discriminating circuit 9, a shutter driving circuit 10, and an electrooptic shutter 11. Excellent stereophonic picture can be obtained through shading off of one focus.

By using both parallaxes, there is a "Q" similar to the above-mentioned conventional device, but in the present invention, it is possible to view stereoscopically by using the K2 information.
When shooting a camera, we take advantage of the property of the eye that even if the image on one side is a little blurry, it does not affect the stereoscopic effect. There is no effect, there is little deterioration in resolution, and if there is some blur, the focus is 0, and the output image difference of the big man camera is 0. The resolution is good, stereoscopic KG is not visible, and on the monitor TV, the outline on one side is slightly blurred and there is little flickering, and the content is not easy to understand. People who view stereoscopic images on a television receiver experience 6% less discomfort.
