  • Patent number: 8866883
    Abstract: Tools are described for preparing digital dental models for use in dental restoration production processes, along with associated systems and methods. Dental modeling is improved by supplementing views of three-dimensional models with still images of the modeled subject matter. Video data acquired during a scan of the model provides a source of still images that can be displayed alongside a rendered three-dimensional model, and the two views (model and still image) may be synchronized to provide a common perspective of the model's subject matter. This approach provides useful visual information for disambiguating surface features of the model during processing steps such as marking a margin of a prepared tooth surface for a restoration.

  • Publication number: 20140267636
    Abstract: An image display device performs control to provide light distribution characteristics in which a light distribution angle is wider in a horizontal direction corresponding to a lateral direction parallel to a direction in which eyes of an observer are arranged, rather than in a vertical direction corresponding to a longitudinal direction perpendicular to the direction in which the eyes of the observer are arranged, to thus obtain a state where the light distribution angle is wider in the horizontal direction, and the occurrence of a luminance difference by an emission angle of video light related to the horizontal direction can be suppressed. That is, it is possible to observe a good image in which the luminance of video light is adjusted and to reduce fatigue in the observer.

  • Patent number: 8717348
    Abstract: System and method for synchronizing shutter glasses with a display system. An embodiment comprises displaying a first image from a first image stream on a display plane, displaying a second image from a second image stream on the display plane, and displaying a synchronization signal on the display plane, during a first, a second, and a third display period, respectively. The first image and the second image are displayed at least partially on the same area of the display plane and the first and the second display periods do not overlap. The display of the synchronization signal on the display plane enables the elimination of a dedicated synchronization signal broadcast unit, thereby reducing the cost while increasing the reliability of a display system.

  • Patent number: 8687050
    Abstract: A test pattern for evaluating L/R crosstalk extinction ratio in a stereoscopic 3D system has a strip of one characteristic—polarization, white, color—associated with a plurality of calibrated chips in a left eye image and a strip of a contrasting characteristic—orthogonal polarization, white, contrasting color—associated with a plurality of calibrated chips in a right eye image such that, when the two images are superimposed, the strip of one image overlays the calibrated chips of the other image. By alternately occluding one eye while observing the superimposed image with the other eye, a portion of the strip of the occluded eye image appears across the chips of the viewing eye image when there is crosstalk. The extinction ratio value associated with the chip of the viewing eye image that most closely matches the portion of the strip from the occluded eye image is an estimate of the L/R crosstalk.
