Three-dimensional video apparatus and methods using composite and mixed images
First Claim
1. A method for producing a three-dimensional illusion of a subject comprising the step of sequentially displaying on a viewing surface images of the subject as formed alternately of a first series of a first type of picture frames and a second series of a second type of a picture frames at a rate within a range of 4 to 30 changes between said first and second series of picture frames per second, said first type of picture frames comprising at least two interlaced images of said subject as viewed from different points of origin and said second type of picture frames comprising at least two interlaced images of said subject as viewed from different points of origin, said images of said first type of picture frames being different in order of point of origin from said second type of picture frames.

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.
