Abstract: The illusion of three-dimensional images is achieved by having a first video camera oriented to view the subject from one point of origin, a second video camera oriented to view the subject from another point of origin, a switching device for alternately coupling first and second series of composite picture frames to a display device including a viewing surface for converting the signals at the output terminal into a visual display on the viewing surface. A composite picture frame includes a first field corresponding to the output of the first video camera and a second field corresponding to the output of the second video camera. A special effects generator can be included to mix the output of the switching device with either the output of the first camera or the second camera to generate a image having a substantial and continuously present component of the images produced thereby.

Abstract: Development of a three-dimensional illusion through sequential displaying on a viewing surface of images of the subject as viewed alternatively first from one point of origin and then, time displaced, from another point of origin at a rate within a range of 4 to 30 changes between the points of origin per second. The effect of the illusion is maximized by having the points of origin vertically aligned with respect to one another and having the points of origin displaced from one another a distance less than normal interoccular distance.
