Abstract
The present invention is a general mode of a pixel-based adaptive blending method. By receiving several different input signals to generate a pixel and a blending factor of each signal, an output pixel can be generated depending on these pixels and blending factors. Thus, several different video and graphic images can be overlapped and blended flexibly on an output display.
