  • Patent number: 11443715
    Abstract: A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at the display device, wherein the display device is to use an illumination strobe during each frame period associated with a corresponding frame of the sequence of frames. The rendering device further is to determine a position of the illumination strobe within each frame period based one or more input parameters, each input parameter representing a corresponding operational characteristic of one of the rendering device or the display device.

  • Patent number: 11430409
    Abstract: A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at a frame rate and to set an illumination configuration to be applied by the display device during a frame period for each frame of the sequence of frames based on the frame rate. The illumination configuration controls at least one of an illumination level and a duration for an illumination strobe, and at least one of an illumination level for an illumination fill preceding the illumination strobe in the frame period and an illumination level for an illumination fill following the illumination strobe in the frame period. The display device is to receive a representation of the illumination configuration from the rendering device and apply the illumination configuration during a frame period for each frame of the sequence of frames to display the frame.

  • Patent number: 11183150
    Abstract: A display system includes a display device and a rendering device having a plurality of individually-controllable illumination regions. The rendering device is to render a frame for display at the display device during a frame period, to determine a gaze position of a user relative to the display device for the frame period, and to set, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period or a subsequent frame period based on a classification of the illumination region that is representative of a location of the gaze position relative to the illumination region.

  • Patent number: 8405779
    Abstract: A video decoder block provides a common pathway for processing video signals encoded using different video formats. The video decoder block passes the video signals through the same processing components in order convert the signals to a common format for display or storage. Each processing component can be disabled or by-passed to enable or disable the function performed by the component. This reduces the number of components and signal processors required in devices that need to accommodate signals of different formats.

  • Patent number: 6462786
    Abstract: A method and apparatus for blending a plurality of image input layers include processing that begins by converting each of a plurality of image input layers that have a color base that differs from a color base of a display into a image layer having the color base of the display, thereby producing converting image layers. The color base of the image input layers and of the output include the colorimetries of various standardized video signals, color space, and/or any other defining display characteristics of video signals that is currently standardized or maybe standardized. Further note that an image input layer corresponds to a window, a background and/or a display area of a display, where the display is capable of presenting more than one image, where the images originate from different video and/or graphics data sources (e.g., a television signal, and a computer application display).
