  • Patent number: 4008482
    Abstract: The system involves splitting the light spectrum from a color picture to be reduced in size into first and second spectral portions which are simultaneously photographed with black and white film. The black and white film can be reduced to an extremely small size for storage. Reproduction of the color picture is accomplished by projecting simultaneously from both black and white film images the respective light spectral portions and recombining them to produce the full color picture.

  • Patent number: 3976837
    Abstract: A picture in the form of a print or projected image onto a rear view screen in a suitable mounting is positioned in a vertical plane and the mounting then rotated extremely rapidly about a vertical axis exactly bisecting the picture in the plane. With this arrangement, each person in an audience surrounding the mounting over 360.degree. can view the picture each time the viewer's line of sight is normal to the plane of the picture so that, in effect, the entire audience regardless of their position over 360.degree. can view the single picture simultaneously.
