Method and Apparatus for Fast and Flexible Digital Image Compression Using Programmable Sprite Buffer

摘要

A system and method of performing digital image compression comprises comparing pixels in various locations in a digital picture image frame; coding a position of pixels located in a foreground of the digital picture image frame; sending the coded positions of the pixels located in a foreground of the digital picture image frame to a frame buffer of a sprite controller; separating a background pixel group from a foreground pixel group in the digital picture image frame based on the coded positions; compressing the pixels in the foreground pixel group; and transmitting a frame number and a frame buffer parameter dimension corresponding to the compressed pixels to a digital picture image display viewer.
