Abstract
In a pixel imaging method and system, pixel information is stored into backing stores in system memory of a computer. A graphics processing unit (GPU) composites the pixel information into a first assembly buffer that has a first color depth of at least greater than 8-bits per color component. The GPU dithers and filters the pixel information in the first assembly buffer into a second assembly buffer. The second assembly buffer has a second color depth that is different from the first color depth of the first assembly but is the same as the color depth of the computer's frame buffer. The GPU copies the pixel information from the second assembly buffer into the frame buffer (optionally modifying them such as, by filtering), and scan-out hardware outputs the pixel information in the frame buffer to a display of the computer.
