Abstract
An advanced dot-stretch anti-sparkle technique analyzes the stream of display pixels to determine an optimal time for performing the dot-stretch operation. The system searches the stream of display pixels for a current and previous pixel that are the same color. The system then performs the host access and the dot-stretch during the pixel match. If a pixel match is not detected within a predetermined period of time, the search for two matching pixels is abandoned and the dot-stretch process is implemented.
