  • Method and apparatus for image processing
    Patent number: 7711188
    Abstract: The present application relates to a method of processing data corresponding to an image (42; 52; 68; 70; 78, 80; 98). The method includes the step of generating an identifier (56, 58, 60, 62; 74, 76; 83, 84; 91, 92, 93) for identifying a region of the image (42; 52; 68; 70; 78, 80; 98) to which a block of said data relates; and then storing the identifier (56, 58, 60, 62; 74, 76; 83, 84; 91, 92, 93). The application further relates to apparatus for processing data corresponding to an image (42; 52; 68; 70; 78, 80; 98).
    Type: Grant
    Filed: April 12, 2006
    Date of Patent: May 4, 2010

  • Method and apparatus for image processing
    Patent number: 7506240
    Abstract: The present application relates to a method of at least substantially synchronizing data output from at least first and second graphics cards (1, 2). A synchronization difference between the first graphics card (1) and the second graphics card (2) is determined and a correction signal (41) generated based on the synchronization difference. The correction signal (41) is supplied to the second graphics card and the operating frequency of the second graphics card (2) is adjusted in response to the correction signal (41). The application also relates to a system (100) for processing images.

    Publication number: 20060012540
    Abstract: The present application relates to a method of at least substantially synchronising data output from at least first and second graphics cards (1, 2). A synchronisation difference between the first graphics card (1) and the second graphics card (2) is determined and a correction signal (41) generated based on the synchronisation difference. The correction signal (41) is supplied to the second graphics card and the operating frequency of the second graphics card (2) is adjusted in response to the correction signal (41). The application also relates to a system (100) for processing images.
