Abstract
An improved system and method for selectively applying LCD Response Time Compensation (LRTC) to areas of an LCD panel containing video motion. Motion vectors contained within macroblocks in a compressed video stream are utilized to qualify whether individual pixels in a video frame are a candidate for LRTC. In various embodiments of the invention, computationally expensive LRTC can be selectively applied, pixel-by-pixel, which can result in portable information system power savings by reducing the number of computational cycles and the amount of graphics controller power overhead.
