  • Publication number: 20060033997
    Abstract: Micro-displays used for front or rear projection systems as well as near-eye viewing systems may be enhanced using embodiments of the present invention. In one embodiment, the invention may include an array of micromechanical optical modulators, an electronic control system for operating the optical modulators in accordance with a received video signal, and an overlayer for the array of modulators to modify the fill factor for incident light on the array of modulators, the incident light corresponding to at least one color constituent of a video signal.
    Type: Application

  • Publication number: 20040212704
    Abstract: A method to reduce the effect of noise on a pixel sensor element includes accumulating charge during an image capture operation (the accumulated charge representing a combination of noise and image), and discharging the accumulated charge for a predetermined time to generate a pixel sensor signal. The act of discharging may be passive or active.
