Abstract
In particular embodiments, a computing system may receive receiving a first image frame of a sequence of image frames to be shown on a display having a plurality of backlight zones. The computing system may compute backlight unit statistics of the first image frame. The backlight unit statistics may represent grayscale levels for the plurality of backlight zones. The computing system may compute a global dimming gain for adjusting color values and backlight unit intensity of a second image frame of the sequence of image frames based on the backlight unit statistics of the first image frame. The computing system may adjust, using the global dimming gain, the color values and the backlight unit intensity of the second image frame.
