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, a non-picture portion, and a subtitle which is superimposed on at least a subset of the non-picture portion, where the non-picture portion has an initial brightness value. Then, the system scales the brightness of pixels corresponding to a remainder of the non-picture portion of the video image to have a new brightness value that is greater than the initial brightness value to reduce user-perceived changes in the video image associated with backlighting of a display that displays the video image, where the remainder of the non-picture portion excludes the subset of the non-picture portion.
