Abstract
A display concept designed to interface with source material from a computer, video recorder or video camera. The interface to a computer generates a series of images that are separate viewpoints of a desired scene to be viewed in three dimensions. The images are based upon a horizontal translation of viewpoints. In the case of a video camera, the interface captures video images from multiple viewpoints and delivers these images in a successive manner to a location at which they can be viewed. The camera requires a single lens and sensor instead of multiple lenses. In the video recorder case, an interface stores images from a computer or video camera and plays back images in the proper sequence for the display. A display system can also operate as a film recorder to provide hard copy, three-dimensional images. A computer, video recorder or video camera thus provides images to a surface which can be viewed and which can present two-dimensional images which are changeable into three-dimensional images. In this way, the output from a computer, video recorder or a video camera can be used to store images and to play back the images in the proper sequence for a three-dimensional display…
