Three dimensional television system
First Claim
1. A method of displaying by projecting a stereo pair of images to present a single three dimensional image to normal human perception comprising the steps of positioning a pair of video cameras in stereo relation to each other to view a scene, switching the video signal from first one camera and then the other camera, controlling the time interval that each of the cameras is operative so that one camera is active nearly all of the time while the other camera is active only briefly, synchronizing the video of the two cameras and switched video signals, and transmitting and displaying the switched video signals on a conventional television receiver thereby allowing the human visual perception process to interpret the switched signals as a single three dimensional image.

Abstract
Method and apparatus for producing a three dimensional television image by presenting stereoptican pairs of images to the viewers eyes. One of the stereoptican partners is presented most of the time while the second stereoptican partner is flashed on and off rapidly. Under the proper conditions with the second stereoptican partner being flashed on for a suitably short period of time at the proper repetition rate, the viewer is not consciously aware of its presence and effectively perceives the picture as a three dimensional image.

- 5. Apparatus for producing a television video signal which appears as a three dimensional image to human visual perception when displayed on a suitable conventional television receiver, said apparatus comprising a pair of television cameras positioned in stereo relation to each other, an electronic video switch operatively connected to said cameras for passing first the video from one camera and then the video from the other camera, a controller operatively connected to said electronic video switch for controlling said video switch to allow the video from one camera to pass nearly all of the time but to interrupt the video from the other camera to pass for a brief instant several times each second, a synchronization generator operatively connected to said cameras and said controller for synchronizing said controller and the video of the two cameras and means for transmitting and displaying the video signals on a suitable television receiver.
