    Abstract: Three-dimensional information is presented directly on the surface of a target three-dimensional object without using a display device such as a display monitor and an HUD. Spatially coded light patterns are projected from two projectors on a target object surface. The light projected from the two projectors are added up on the object surface to produce unified color and luminance. On the object surface, light is simply added up, so that a pattern whose color and brightness correspond to distance and height appears. Hence, a distance to an object or a three-dimensional shape of an object can be highlighted by the color and brightness presented on the object for perception by human beings.

  • Patent number: 8733938
    Abstract: A virtual-sunroof system for providing a virtual sunroof at an interior of a vehicle for viewing by a passenger of the vehicle. The system includes a virtual-sunroof imaging device configured and arranged at the vehicle to collect image information from an environment above the vehicle and create digital image data using the image information. The system also includes a virtual-sunroof projection device configured and arranged in the vehicle to be in communication with the virtual-sunroof imaging device for providing a virtual sunroof display. The virtual sunroof display provided (a) is viewable above a head of the passenger, (b) is formed using the image data, (c) represents accurately at the interior of the vehicle a rendition of the environment above the vehicle, and (d) has a size, shape, and location corresponding generally to a size, shape, and location that an actual conventional-type sunroof would have in the vehicle.

  • Patent number: 8690339
    Abstract: A hologram projecting system includes a coherent light source for emitting a reference beam onto a real object; and an image sensor for receiving the reference beam and a scattered beam reflected from the real object, and recording a Fourier image of the real object. Also included is a modulator for receiving the Fourier image. The reference beam is passed through the modulator, and configured to interact with the Fourier image to form a virtual image of the real object. The image sensor includes an n×m pixel array, where n and m are numbers of rows and columns, respectively. The modulator includes an n×m pixel array corresponding to the n×m pixel array of the image sensor. The pixels in the n×m pixel array of the image sensor control transmissivity of light in corresponding pixels of the n×m pixel array of the modulator.

  • Publication number: 20140092365
    Abstract: To provide a space image forming element realizing higher reflectance and larger area by making aperture ratio and transmittance higher and a method of manufacturing the same, thereby realizing high reflectance and, as a result, formation of an image having high brightness in the air. In a space image forming element of the present invention, a light transmission region is configured by a transparent pattern formed by exposure process using a transparent resist. By forming a metal layer between adjacent transparent patterns, a mirror-face region is formed in the interface between a side wall of the transparent pattern and the metal layer. The metal layer has a two-layer structure. The second metal layer is formed by electroplating using the metal in the first layer as an electrode.

  • Patent number: 8648773
    Abstract: A light ray controller has a circular frustum shape and is fitted in a circular hole of a top board such that its large diameter bottom opening faces upward. The light ray controller transmits a light ray while diffusing the light ray in a ridgeline direction and transmits the light ray straightforward without diffusing the light ray in a circumferential direction. A rotation module is provided under the table. One or more scanning projectors are provided on a circumference around an axis of the light ray controller on the rotation base of the rotation module. One or more scanning projectors are rotated by the rotation module. The controller controls one or more scanning projectors being rotated based on three-dimensional shape data stored in a storage.

  • Publication number: 20140002800
    Abstract: An apparatus projecting or displaying images to a viewer. The apparatus or Pepper's ghost system projects or displays an image stream onto a reflective element with a first surface receiving and reflecting a portion of light associated with the image stream to the viewer and a second surface opposite the first surface. The apparatus includes a cleaning assembly including an air supply providing a volume of flowing air and an ionizing mechanism for receiving the flowing air and outputting an ionized air flow. The ionized air flow is directed over the second surface of the reflective element. The reflective element is positioned at a non-vertical display angle. An outlet of the cleaning assembly is positioned adjacent an upper edge of the reflective element, and the ionized air flow is output from nozzles as laminar air flow with a flow rate chosen to mitigate dust collection on the upper second surface.

  • Patent number: 8591035
    Abstract: A display device includes a projector, a Fresnel lens converting a projected light from the projector into a nearly parallelized light, a screen with light reflectivity on which an image by the projected light from the projector is generated, and a retrotransmissive material forming another image of an image located on one side of an element plane in a position in a space on the other side of the element plane such that the image and the other image are symmetric with respect to the element plane. The retrotransmissive material forms an image by a light that has obliquely entered the element plane, such that a position from which the light has obliquely entered the element plane and a position in which the image is formed are symmetric with respect to the element plane, and thereby forms a real image of the image on the screen.

    Abstract: A 3D display system using a planar sheet of mist or water droplets as a rear projection screen. The system includes a screen generation assembly with a nozzle configured to convert supply water into a screen of water droplets. The screen is substantially planar and has a front surface facing a viewing area and an opposite rear surface. The display system includes a projection assembly projecting 3D content onto the rear surface. The projection assembly includes a first projector projecting left eye images and a second projector projecting right eye images. The 3D content may be provided using polarization or other 3D technology. For example, the first projector includes a first interference filter and the second projector includes a second interference filter differing from the first interference filter, whereby the left and right eye images are presented concurrently on the rear surface with differing bands of the visible color spectrum.
