Abstract
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.
