  • Publication number: 20110305029
    Abstract: An illuminating system having an electronic shield illuminating apparatus comprises a semiconductor light-emitting source, a reflector, an electronic shield, a shield driving control circuit, and a projection lens. The reflector is intended for reflecting a portion of the light reflected by the semiconductor light-emitting source, and has a reflecting surface facing the semiconductor light-emitting source. The electronic shield is intended for generating different shield patterns to mask the light emitted by the semiconductor light-emitting source, and the light reflected by the reflector, and has a main surface facing the semiconductor light-emitting source and the reflecting surface of the reflector. The shield driving control circuit drives the electronic shield to generate different shield patterns in response to a signal information. The projection lens projects the light passing through the electronic shield.

  • Publication number: 20110304689
    Abstract: A method for modifying images for display on a three dimensional display includes receiving a first image and a corresponding second image which together represent a three dimensional image when displayed on the display. Glasses suitable to be worn by a viewer of the display provide depth perception of the three dimensional image. The glasses selectively send a signal to the display indicating whether the viewer selectively observes either two dimensional or three dimensional content by the display. The glasses also selectively send a signal to the display indicating the depth strength and image brightness of the perceived images.

  • Patent number: 8073196
    Abstract: Among other things, methods, systems and computer program products are described for detecting and tracking a moving object in a scene. One or more residual pixels are identified from video data. At least two geometric constraints are applied to the identified one or more residual pixels. A disparity of the one or more residual pixels to the applied at least two geometric constraints is calculated. Based on the detected disparity, the one or more residual pixels are classified as belonging to parallax or independent motion and the parallax classified residual pixels are filtered. Further, a moving object is tracked in the video data. Tracking the object includes representing the detected disparity in probabilistic likelihood models. Tracking the object also includes accumulating the probabilistic likelihood models within a number of frames during the parallax filtering.

  • Publication number: 20110074933
    Abstract: A method for modifying images for display on a three dimensional display includes receiving a first image and a corresponding second image which together represent a three dimensional image when displayed on the three dimensional display. Based upon the first and second image, the method determines whether their content is expected to cause substantial discomfort to a viewer when displayed on the three dimensional display. At least one of the first and second images are modified based at least in part on a physical value related to the pixel pitch of the display, in such a manner to reduce the expected discomfort to the viewer.
