Benefits of technology

The patent describes a method and device for updating computer-graphic images. The method involves coding the positions of pixels in a foreground of an image frame, separating a background pixel group from the foreground, updating only the pixels in the foreground, and transmitting the updated pixels to a display viewer. The device includes a sprite controller that performs these functions. The technical effects of this patent include improved efficiency in updating computer-graphic images and improved image quality.

Problems solved by technology

However, it generally does not work well with nature-looking computer animation such as computer games and computer-generated animation movie clips, etc. with nature scenes.
Thus, the CPU and associated graphic engine 102 as well as the bus input / output (I / O) system are busying processing those pixels evenly; thereby creating I / O and CPU jam.
Accordingly, the above reasons represent limited processing efficiency for nature like computer graphic image display.

Abstract

A technique for updating computer-graphic digital images comprises coding a position of pixels located in a foreground of a computer-graphic image frame; sending the coded positions of the pixels located in the foreground of the computer-graphic image frame to a frame buffer of a sprite controller; separating a background pixel group from a foreground pixel group in the computer-graphic image frame based on the coded positions; updating the pixels in the foreground pixel group only; and transmitting a frame number and a frame buffer parameter dimension corresponding to the updated pixels to a computer-graphic image display viewer.
