  • Patent number: 10043457
    Abstract: A display for a computer system, such as an LCD, is configured to consume less power when compared to conventional designs. The display includes a screen and at least one backlight configured to illuminate the screen. An input to the at least one backlight is adjustable to produce a desired level of brightness. The input may be computed based on a generated source image and a defined constraint. An input to the display is computed based on the input to the at least one backlight and the source image. The input to the display modifies the level of brightness provided by the at least one backlight to produce a viewable image.

  • Patent number: 8872754
    Abstract: A system, method, and computer program product are provided for controlling stereo glasses shutters. In use, a right eye shutter of stereo glasses is controlled to switch between a closed orientation and an open orientation. Further, a left eye shutter of the stereo glasses is controlled to switch between the closed orientation and the open orientation. To this end, the right eye shutter and the left eye shutter of the stereo glasses may be controlled such that the right eye shutter and the left eye shutter simultaneously remain in the closed orientation for a predetermined amount of time.

  • Patent number: 8692844
    Abstract: A method and system are disclosed for antialiased rendering a plurality of pixels in a computer system. The method and system comprise providing a fixed storage area and providing a plurality of sequential format levels for the plurality of pixels within the fixed storage area. The plurality of format levels represent pixels with varying degrees of complexity in subpixel geometry visible within the pixel. A system and method in accordance with the present invention provides at least the following format levels: one-fragment format, used when one surface fully covers a pixel; two-fragment format, used when two surfaces together cover a pixel; and multisample format, used when three or more surfaces cover a pixel. The method and system further comprise storing the plurality of pixels at a lowest appropriate format level within the fixed storage area, so that a minimum amount of data is transferred to and from the fixed storage area.

  • Patent number: 7683905
    Abstract: Apparatuses and methods for detecting position conflicts during fragment processing are described. Prior to executing a program on a fragment, a conflict detection unit, within a fragment processor checks if there is a position conflict indicating a RAW (read after write) hazard may exist. A RAW hazard exists when there is a pending write to a destination location that source data will be read from during execution of the program. When the fragment enters a processing pipeline, each destination location that may be written during the processing of the fragment is entered in conflict detection unit. During processing, the conflict detection unit is updated when a pending write to a destination location is completed.
