  • Patent number: 7305088
    Abstract: A motion-picture distributor (12) uses a computer system (22) to convert video signals from a master film (14) into serial video data (41) complying with DVD-Video standards. Further, the computer system (22) modifies the sequence of scene-data sets (42-1, 42-2, . . . ) constituting the data (41) and encrypts the data for each scene-data set, thus producing encrypted non-serial video data (45). The data (45) are separated into DVD-ROMs (15-1, 15-2, . . . ), for distribution purposes. A theater (13) then uses a serialization apparatus (51) to read the data (45) from the DVD-ROMs (15-1, 15-2, . . . ), and sorts the scene-data sets in a correct sequence, thus producing encrypted serial video data (80). A motion picture projector (52) decrypts the data (80), thereby preparing the data (41). The data (41) are played back to view a movie. On the other hand, a movie distributor (12) may distribute the DVD-ROMs in a separated manner.

Images of a scene being photographed, as viewed through the lens aperture in its various disparity positions, are recorded for subsequent display, which produces a three dimensional illusion when viewed on a conventional display with the unaided eye. The size of the lens aperture and the parallax scanning pattern are adjustable to suit conditions. The lens aperture may be defined by a through-hole in an opaque card, a plurality of interleaved leaf elements, or a planar array of cells switched between transparent and opaque states.

  • Patent number: 4963015
    Abstract: A method of recording an image of a scene onto cinematographic color film comprises forming a number of successive partial images through a single lens system onto each single frame of the film, the successive partial images being recorded in light of different characteristics, for example different colors. The film is projected using a conventional projector, and when viewed through appropriate filters, gives a stereo scopic effect. To get an optimum effect, the sequence in which the images are recorded should be appropriate to the predominant direction of horizontal movement in the scene. Accordingly in one form of the invention, each image is divided into a number of areas, each area in successive images being recorded in light of different characteristics, and each image having different areas recorded in light of different characteristics.

    Abstract: Paired movie cameras, each having synchronized movements and in phase shutters, are provided with focus and zoom optics of identical, but conventional and commercial manufacture. The paired lenses are first rotated relative to one another to obtain a coincidence between the centration vector for each lens for either zoom or focus. Once the centration vectors are aligned identically on a polar basis, mounting to the camera with provision for synchronous zoom between the respective cameras thereafter occurs. Typically, and before each stereo shooting, the zoom optics are set to a maximum magnification and registered to the appropriate distance with the lens finders and reticules. Upon change of the focus and/or zoom setting, a variable prism affixed to one camera is moved relative to the remaining camera to maintain identical centration between the respective lens cameras.
