  • Patent number: 7740359
    Abstract: An apparatus for displaying images from a video projector. The apparatus includes a virtual projector screen assembly with an elongate screen element, such as a rod, that is mounted at one end to a base. The base is adapted for pivoting about its axis, arid a driver mechanism pivots the, base at high frequencies. During operation, the screen element oscillates between two edge positions with images projected from the projector being displayed on a side of the screen element facing or proximate to the projector. The two edge positions can be thought of as intersecting at the base and define a sweep angle (e.g., the angular difference between the two outer travel points of the screen element that is typically less than about 90 degrees). The driver may include a motor with an oscillating output shaft that pivots the base such as with a belt attached to the base.

  • Patent number: 7229176
    Abstract: Device for displaying imagery three-dimensionally, which comprises a first image reproduction element having an image reproduction surface and a second image reproduction element having an image indication surface of reflective property. Those image reproduction and indication surfaces are in an opposedly facing relation with each other, such that an imagery reproduced and indicated on the image reproduction surface is reflected by the image indicating surface to form a reflected imagery which is viewed by the eyes of person as if it was a three-dimensional image. One or both of such image reproduction and indication surfaces may be curved to have convex and concave surface sides, wherein the concave surface side is formed to have diffuse reflective property. The convex surface sides respective of those two surfaces may be in an opposedly facing relation with each other. Preferably, such two surfaces may each be a screen of light-transmissive type.

  • Patent number: 7226167
    Abstract: An autostereoscopic optical apparatus (10) for viewing a stereoscopic image comprising a left image to be viewed by an observer (12) at a left viewing pupil (14l) and a right image to be viewed by the observer at a right viewing pupil (14r). A left image generation system (70l) forms a left curved intermediate image near the focal surface (22) of a curved mirror (24). A right image generation system (70r) forms a right intermediate image near the focal surface of the curved mirror. A center of curvature of the curved mirror is placed substantially optically midway between the exit pupil and the left optical system (110l) the exit pupil of the right optical system (110r). A beamsplitter is disposed between the focal surface and the center of curvature of the curved mirror.

  • Patent number: 7222966
    Abstract: A method and system are provided for projecting a three dimensional image. A projection system may include a holding tank for storing a reservoir containing a projection medium and a projector including a plurality of valves for projecting the medium from the holding tank. The projection system may also include an illumination device for illuminating the projected medium and a receiving mechanism for receiving the projection medium after illumination. The projection system may also include imaging data computation apparatus for computing imaging data, communication and control tools for communicating the imaging data to the projector in order to control valves for dispersing the projection medium, and an illumination control unit that controls an illumination device for illuminated the dispersed medium.

  • Patent number: 7180663
    Abstract: When any observer receives an image of a scene having the same relative size, shape and location on the retina of each of his two eyes at any instant and the image of the scene has some component of horizontal motion in any direction, the image viewed is three dimensional. If the motion occurs, all scene-object points are spatially located in playback since all of the original ray angles between camera and scene points are reproduced for both eyes by the ray cross-overs at the scene image points. When successive frames are presented, the brain cognizes the motion in linking the frames by persistence of vision. For the brain to perceive an item as moving it must connect these frames, but because of intersecting rays coming from any spatial location in successive frames, the brain cannot connect the frames without also locating the points in space.

  • Patent number: 7168808
    Abstract: An apparatus for viewing an image includes a screen on which an image of a superimposed projection for left and right eye views of a viewer is displayed image. The apparatus includes a mechanism for projecting the projections onto the screen image. The apparatus includes a rear retarder disposed in front of the screen image. The apparatus includes a front retarder disposed in front of the rear retarder image. The apparatus includes a mechanism for applying an increasing ramp of phase retardance across an image in the rear retarder, and applying a decreasing ramp of phase retardance across the image in the front retarder so a constant phase retardance is created across an entire surface of the screen disposed behind the rear retarder and the front retarder when seen by a viewer in front of the front retarder.

  • Patent number: 7165842
    Abstract: An improved autostereoscopic display apparatus (10) forms left and right virtual images for pupil imaging by forming, through a beamsplitter (16), a real intermediate image near the focal surface of a curved mirror (24). A circular polarizer (90) is disposed at a position between viewing pupils (14l, 14r) and the beamsplitter (16), minimizing glare due to stray light reflection from the curved mirror surface.

  • Patent number: 7144114
    Abstract: The invention provides systems and methods for generating a visual image that is made to appear to be situated behind an architectural structure, such as a wall of a building, and is viewed through windows thereof. The image appears as an oversize object relative to the actual object. The system and method include an image recorder and/or a pre-recorded image, an image display apparatus, and a mask. Sound can be provided as required to complete the illusion. The image can be a still image or a moving image. In some embodiments, two viewers can see the image from opposite sides of the structure, each perceiving the image as being on the side opposite to the viewer. The system includes a video capture device and a display and an optional audio system for showing the person whose image is being projected the giant image as seen and heard by a viewer.

  • Patent number: 7144113
    Abstract: A virtual image display apparatus comprises a pair of optical projection systems, each having a display device, a light source and a projection lens. The images formed on the display device are projected to an image location optical system, which comprises a light collecting lens and an optical diffusion device. The light rays from the optical projection systems are reflected at a translucent reflecting means, so that the light rays are respectively collected at right and left eyes of an observing person. As a result, the images can be recognized by the person as a virtual image in the distance. Since the optical diffusion device diffuses the light rays, in such a way that the light rays to one of observing eyes may not reach the other observing eye, so that the image information of the respective light rays can be recognized by the observing person, without causing a cross-talk.

  • Patent number: 7097307
    Abstract: The invention provides systems and methods for generating a visual image that is made to appear to be situated behind an architectural structure, such as a wall of a building, and is viewed through windows thereof. The image appears as an oversize object relative to the actual object. The system and method include an image recorder and/or a pre-recorded image, an image display apparatus, and a mask. Upon being projected, the image of interest is masked so that illumination falls on one or more regions of a display surface, and no illumination reaches the architectural structure outside the display region(s). Sound can be provided as required to complete the illusion. The image can be a still image or a moving image. In some embodiments, two viewers can see the image from opposite sides of the structure, each perceiving the image as being on the side opposite to the viewer.
