  • Patent number: 10241545
    Abstract: A distortion calibration system generates a distortion map for a head-mounted display (HMD). The system includes a camera that takes pictures of a test pattern displayed by the HMD. The images are taken at different camera positions and/or states of the HMD. The system determines a distortion map using the captured images, and uploads it to the HMD as part of, e.g., an optical model. The HMD comprises an electronic display, an eye tracking unit, an optics block, and a module. The module estimates distortion values based on eye tracking information from the eye tracking unit, an optical model, and a state of the HMD (e.g., a distance between the optics block and the electronic display). The module determines an adjusted state of the HMD using the estimated distortion values, the eye tracking information, and the optical model, and adjusts the state of the HMD to the adjusted state.

  • Patent number: 9986227
    Abstract: An apparatus for displaying three dimensional (3D) images to a viewer without the need for 3D glasses. The apparatus includes a display element with a lenticular display surface that is supported to be horizontal and face upward into a viewing space. The apparatus includes a location tracking element tracking a location of a viewer in the viewing space relative to the lenticular display surface. The apparatus includes a display controller generating reprojected content for operating the display element to display 3D images via the lenticular display surface. The reprojected content is generated by determining for each pixel of the display element the content or images passing through tracked and/or determined eye locations and then remapping content delivered to each of the pixels of the display element to achieve a predefined pattern of content in viewpoints of fixed camera positions for the display element.

  • Patent number: 8922630
    Abstract: A projector includes a discharge lamp, a discharge lamp driver that supplies the discharge lamp with a current, and a controller that controls the discharge lamp driver. The controller controls the discharge lamp driver in such a way that the absolute magnitude of the current is relatively small in the first period and relatively large in the second period. In the second period, the controller carries out a second-period AC control process in which an AC current is supplied to the discharge lamp. In the first period, the controller carries out a first-period control process in which in a third period, the absolute magnitude of the current becomes a minimum in the first period and in a fourth period, the absolute magnitude of the current becomes an intermediate value between the minimum and a maximum absolute magnitude of the current in the second period.

  • Patent number: 8908010
    Abstract: A method of processing a video input, having a first video bitstream transmitting pictures of a first view and a second video bitstream transmitting pictures of a second view, includes: checking the video input to detect if a first picture of one of the first and second views is correctly paired with a second picture of the other of the first and second views for specific presentation time; and referring to a detecting result for selectively performing a predetermined processing operation upon the video input. The video input transmits the second picture while transmitting the first picture. When the detecting result indicates that the first picture is not correctly paired with the second picture for the specific presentation time, both of the first picture and the second picture are skipped, and previous pictures that are correctly paired with each other for the specific presentation time is repeated.

  • Patent number: 8902301
    Abstract: An organic electroluminescence display includes pixels in a matrix that each emits visible light. A data line driver supplies a video signal to each pixel. The video signal includes first and second frames corresponding to first-eye and second-eye image information. A scanning line driver distributes a scanning signal to each pixel for controlling a supply of the video signal. The display includes an emitter in an arrangement position of the pixels in the matrix. The emitter emits infrared light in a same direction as the visible light. The scanning line driver supplies a control signal to the emitter that indicates a switching timing between the first frame and the second frame, and causes the emitter to emit the infrared light based on the control signal for reception by eye glasses for controlling opening and closing of electronic shutters.

  • Patent number: 8896670
    Abstract: An image processing device includes a distance data analysis unit that analyzes subject distance information with the partial region units of captured images having different viewpoints, and a data generation unit that determines whether a recorded image or an output image is set to a two-dimensional image or set to a three-dimensional image depending on the analysis result, and generates the recorded or output image based on the determination result, wherein the data generation unit determines a recall level of stereoscopic vision in three-dimensional display based on the analysis result, and if it is determined that the recall level of stereoscopic vision is low, generates a two-dimensional image as the recorded or output image, and if it is determined that the recall level of stereoscopic vision is high, generates a three-dimensional image as the recorded or output image.

  • Patent number: 8896676
    Abstract: A 3D video viewing shutter device receives display response time from a 3D video display device for determining shutter open and close times. Response time may correspond to display type, a particular display and/or a change in pixel illumination levels between frames. The shutter device receives response information during device initialization and/or corresponding to changing pixel illumination levels. A sequence of 3D frames may comprise a pattern of left frames, right frames, blank frames and/or frames comprising a combination of left and right frames. Based on display device and/or shutter device response times, the shutter device may extend shutter transmittance time during a frame display interval into a blank frame interval. Transmittance may be enabled during display of blank frames subsequent to left or right frames. The shutter device and display device may communicate via a wireless link for example, via a Bluetooth wireless link utilizing Bluetooth clocks.

  • 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.
