  • Patent number: 10110653
    Abstract: A server receives an update image for transmission to a client and encodes and compresses the update image data using a progressive encoding scheme. In one embodiment, the image data is encoded using progressive JPEG encoding and then into a base64 text string. When insufficient network bandwidth is available to transmit all of the image data for the update image, the server transmits only a first portion of the encoded image data, which is sufficient to fully reproduce the original update image but at a lower quality. When more network bandwidth becomes available, an additional portion of the encoded image data is transmitted to the client. The client is able to append the additional portion to the first portion to refine the image represented at the client. This mechanism may be implemented using unmodified web browsers and servers to remote a computer graphical user interface display.

  • Patent number: 7978194
    Abstract: A method and apparatus for hierarchical Z buffering stenciling includes comparing an input tile Z value range with a hierarchical Z value range and a stencil code. The method and apparatus also updates the hierarchical Z value range and stencil code in response the comparison and determines whether to render a plurality of pixels within the input tile based on the comparison of the input tile Z value range with the hierarchical Z value range and stencil code. In determining whether to render the tile, a stencil test and a hierarchical Z value test is performed. If one of the test fails, the tile is killed as it is determined that the pixels are not visible in the graphical output. If the stencil test passes and the hierarchical Z test passes, the pixels within the tile are rendered, as it is determined that the pixels may be visible.

  • Patent number: 7792622
    Abstract: The method and system for vehicular guidance comprises an imaging device for collecting color image data to facilitate distinguishing crop image data (e.g., crop rows) from background data. A definer defines a series of scan line segments generally perpendicular to a transverse axis of the vehicle or of the imaging device. An intensity evaluator determines scan line intensity data for each of the scan line segments. An alignment detector (e.g., search engine) identifies a preferential heading of the vehicle that is generally aligned with respect to a crop feature, associated with the crop image data, based on the determined scan line intensity meeting or exceeding a maximum value or minimum threshold value.

  • Patent number: 7755649
    Abstract: Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast.

  • Patent number: 7705855
    Abstract: A display system includes a subpixelated display panel having subpixels in two saturated primary colors. In one embodiment, the primary colors are selected so as to be a substantially metameric pair for an achromatic color such as white. Information display efficiencies arise from utilizing a checkerboard arrangement for the two primary colored subpixels and from using subpixel rendering algorithms to render an image on the display. The bichromatic display may display a black and white image combined with a monochromatic image, or may provide the capability to overlay a first image from a first image source carried on a chromatic channel onto a second image from a second image source carried on a luminance channel, where the first image source detects light wavelengths that the Human Vision System is not sensitive to, such as infrared light. This latter embodiment of the bichromatic display system is suitable for night vision devices.
