Abstract
Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a video image, that when displayed, includes a picture portion and the non-picture portion, where the non-picture portion has a first brightness value. Then, the system scales the non-picture portion to have a second brightness value that is greater than the first brightness value to reduce user-perceived changes in the video image associated with backlighting of a display that displays the video image.
