ABSTRACT:
My invention is a three-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 and video recorders and synthesizes three-dimensional images from several lateral vantage points in the scene. The playback equipment uses a single lamp and a circular and slowly rotating platform upon which several identical projectors are affixed. The angular velocity of each projection lens node and its corresponding image surface is identical to achieve image motion compensation. Multiple images are simultaneously projected in the direction of a concaved screen through the rotation axis or another point closer to the screen. The screen is semi-specular with horizontal reflecting and vertical scatter properties. The screen in conjunction with the rotating projection nodes, generate vertical aerial exit slits in the space between the audience and the screen. Observers view the 3-D scene by means of several vertical lines of the right and left composite pictures scanned simultaneously by several vertical aerial exit slits which generate the whole picture at conventional refresh rates to avoid flicker.
