Attorney, Agent or Firm:

A system for the production of a second three-dimensional image magnified from a first three-dimensional image in substantially the same proportions, including a first active optical system for creating from the three-dimensional image, a first two-dimensional array. The array is comprised of two-dimensional elemental images. The first active optical system has a number of elements which is equal to the number of elemental images in the array. The configuration of the elements of the first active optical system corresponds to the configuration of the elemental images in the array. The first array is magnified equally in all directions to create a second two-dimensional array comprised also of two-dimensional elemental images. A second active optical system reconstructs a second three-dimensional image that is a magnification of the first three-dimensional image. The second active optical system has an F-number equal to the F-number of the first active optical system. The number of elements in the second active optical system is equal to the number of elemental images in the array. The configuration of the elements in the second active optical system corresponds to the configuration of the elemental images in the array. All of the component parts of an equation for determining the F-number of the second active optical system are the same multiples of all of the component parts used for determining the F-number of the first active optical system, respectively. The multiple is equal to the selected magnification factor.

DETAILED DESCRIPTION These and other objects of the invention which shall be hereinafter apparent are achieved by the SYSTEM AND APPARATUS FOR THE RECORDING AND PROJECTION OF IMAGES IN SUBSTANTIALLY 3-DIMENSIONAL FORMAT comprising a method and apparatus for reducing a three-dimensional scene to an integral photograph and thereafter magnifying the integral photograph as well as the optics used to create the integral photograph by the same scaling factor so as to project a magnified three-dimensional image.
The invention comprises a camera for photographing the scene, a projector for reconstructing the scene in three-dimensions, a screen which is an active optical element in the process and a method of editing motion picture film used in this process.
The invention also includes a method and apparatus for fabricating holograms of live three-dimensional scenes, for projecting magnified three-dimensional images produced from these holograms before large audiences, and for editing motion picture film.
This invention provides a system which is adaptable to animation, home entertainment and computer technology.
