Abstract
Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images, which include a video image, and predicts an increase in an intensity setting of a light source (which is configured to illuminate a display) when the video image is to be displayed based on the color saturation. Then, the system selectively adjusts pixels in the video image associated with a white color filter based on a color saturation of at least a portion of the video image, where the display configured to display the video image includes pixels associated with one or more additional color filters and pixels associated with the white color filter. Next, the system incrementally applies the increase in the intensity setting across at least a subset of the sequence of video images.
