  • Patent number: 7903139
    Abstract: The invention relates to a device which is used to film, record and reproduce video images in real time with a three dimensional appearance, using a video camera and a sonar system in order to obtain the depth information. According to the invention, an electronic system divides up the original image filmed in BGR format and each image is modified in accordance with the depth register (or programming) in order to form new images. Each image corresponds to a determined distance level. The result is displayed on a monitor comprising various independent transparent LCD (liquid crystal display) screens which are aligned one after the other. By displaying the images simultaneously, a single image is formed for the spectator, said image creating an appearance of volume and three-dimensional perception similar to low relief. The depth, video and sound signals are transmitted directly for reproduction purposes and to the magnetic tape recording system for storage purposes, using three magnetic tape heads.

  • Patent number: 7777950
    Abstract: It is made possible to provide a stereoscopic image display apparatus capable of preventing the stereoscopic display characteristics from being degraded even if the locus of light rays between the lens and the two-dimensional display device becomes long. A stereoscopic image display apparatus includes: a plane display device having a display face formed of a plurality of pixels arranged in a matrix form; an optical plate comprising a plurality of lenses which are arranged in front of the display face of the plane display device and which have a uniaxial double refractive material inserted therein, and controlling light rays from the pixels; and a sheet polarizer provided between the plane display device and the optical plate to align a polarization direction of light ray. In the double refractive material, a maximum primary axis of refractive index is parallel to ridgelines of the lenses and is inclined in a direction opposed to a viewer.
