  • Stereoscopic imaging systems using memory affect liquid crystal displays
    Patent number: 5990936
    Abstract: An imaging system includes left and right display panels arranged so as to be viewed separately by left and right eyes of a viewer. A three dimensional video signal is supplied to a drive circuit for the display panels such that image data from the three dimensional video signal is supplied alternately to the left and right display panels. The display panels are of a memory effect LCD type such that, when no image data is received by the display panel, the image data of the previously received field is maintained on display for providing flickerless imaging.

  • Camera adaption for self photography
    Patent number: 5537175
    Abstract: A camera is adapted for self photography by provision of a reflective element disposed over a image receiving means thereof. The reflective element is disposed along or proximate to the focal axis of the image receiving portion for avoiding a parallax effect such that a camera operator may accurately monitor the image during self photography. Several variations on the arrangement of the reflective element allow various photographic effects to be obtained and in addition, the arrangement of the invention may also by applied for effecting audio/visual communication.
