ABSTRACT:
My invention is a threee-dimensional motion picture capture and reproduction method and apparatus that allows multiple viewers to simultaneously watch the reproduction of recorded or real time 3-D pictures without the need for any special optical aids at their eyes. The playback system is compatible with all current forms of film format, television cameras, video recorders and computer graphic signls and synthesizes three-dimensional images from several lateral vantage points in the scene. Scene capture is achieved by computer graphic synthesis, a single translating camera, a few cameras or multiple stationary cameras. The playback equipment consists or multiple stationary projectors with active (light emitting) image planes, astigmatic low f-number projection lenses and a semi-specular screen. The screen vertically scatters the light and either horizontally retro-reflects or plane-mirror reflects the projected light. All projectors project images simultaneously and light projected from any point in the image plane is focused in the vertical plane to vertically scatter but is imaged toward infinity by the projection astigmatic lens horizontally. Parallel light from a distant point is continuous across the screen due to adjacent lateral contiguous lens placement.
