  • Patent number: 10063817
    Abstract: Large format display systems are described that are reconfigurable between an open configuration designed for performing maintenance on the system and a closed configuration designed for normal operations of the display system. In the closed configuration, the display screen is intentionally subjected to a substantial amount of tensile force to advantageously stabilize the display screen. That substantial tensile force is generated by a sturdy stationary frame that the display screen is anchored against in the closed configuration. When the display system is reconfigured to the open configuration, the display system is no longer anchored against the stationary frame. The process of reconfiguring the display system from the closed configuration to the open configuration includes relieving most of the tensile force applied to the display screen using adjustable tensioning mechanisms of the display systems.

Objects moving in either lateral direction can be made to appear closer to or farther away from the viewer depending upon the color of the objects and surrounds. Objects that appear brighter to the left eye appear closer to the viewer when they are moving from left to right. These left eye bright objects appear farther away from the viewer when they are moving from right to left. The effect is reversed for objects that appear brighter to the right eye. Objects that appear brighter to the right eye appear closer to the viewer when they are moving from right to left. These right eye bright objects appear farther away from the viewer when they are moving from left to right. The colors of the areas surrounding moving objects can produce or contribute to the depth effect.

  • Patent number: 5678089
    Abstract: A lens aperture of an autostereoscopic camera is moved in a parallax scanning pattern through a plurality of disparity positions offset from the optical axis of the camera lens. 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. In addition to stereoscopic imaging, the moving lens aperture principle of the present invention may be utilized in range-finding and camera image stabilization applications.

  • Patent number: 5469295
    Abstract: A system and method of collecting and displaying images of isolated persons or objects in three dimensions; whereby isolated images of persons or objects (106) are collected on film or video by digitally removing the background and replacing it with black or collecting the image against a black background (107); and the isolated image (106) is projected with polarized light on to a partially reflective and transparent sheet polarizing screen (104) of an orthogonal polarization sense to that of the projected light. The screen stops and reflects the image (105), but the screen is partially-transparent to light polarized parallel to its polarization sense making a real three dimensional physical object (103B) behind the screen visible from a position in front of the screen. The isolated image (105) on the screen (104) in the presence of real physical three dimensional objects (103A) and (103B) appears to be three dimensional.

  • Patent number: 5159362
    Abstract: A dimensional transformation apparatus and related method for creating visual effects for use in live and prerecorded entertainment. The system engages an elastic projection screen with a three-dimensional object that corresponds to visual effects to be projected. By application of vacuum between the screen and the object, the screen is conformed in skintight relation to the features of the three dimensional object. An actuator, which includes a pneumatic piston, motivates the three-dimensional object to selectively engage and disengage the projection screen, and may be sequenced with projected animation corresponding to the three-dimensional object so as to create multi-dimensional special effects. A control mechanism, including a computer and timing system, digitally controls and sequences projection, dimensional transformation of the screen and background lighting and sound effects.

  • 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.

  • Patent number: 4934824
    Abstract: A method of recording an image of an object onto cinematographic color film comprises forming a number of successive images of the object through a single lens system onto each frame of the film, the successive images being recorded in light of different characteristics, for example different colors. In a preferred embodiment, each frame of the film is exposed successively to light of two or three different colors. The film is projected using a conventional projector, and when viewed through spectacles consisting of two appropriate filters gives a stereoscopic effect. The method can be used to produce a film which can also be viewed without spectacles, and is found to give enhanced sharpness and color saturation. The invention also includes a moving film camera having a mechanism for interposing a number of filters in the optical path successively during exposure of each frame so that successive images are overlaid on each frame.
