ABSTRACT:
Provided is a method and apparatus for dynamic cross fading. Specifically, an embedded system can display an image produced from a blend of other images. Initially, a first image and a second image are stored in a buffer in a display controller. Then, the display controller extracts pixels from corresponding locations in the first image and the second image. The pixels are combined with weights associated with each image to perform the cross fade calculation. Consequently, the result from the cross fade calculation is transmitted to a display unit connected to the display controller for viewing. The result can also be fetched during a refresh of a panel in the display unit. In either case, the result is transmitted to a display pipe during dynamic cross fading. Thus, any images stored in the buffer remain unchanged.
