Abstract: Method and apparatus for selecting a gamma curve used by a display driver circuit for converting code words provided by a display processing unit to brightness levels based on an operating mode of the computing device. For example, the display processing unit provides code words to the display driver circuit for driving output at a display. Further, the display driver circuit converts the provided code words to analog signal for driving output at the display based on the selected gamma curve.

Abstract: In general, aspects disclosed herein provide techniques for processing video data. Certain aspects provide a method for processing video data comprising a plurality of frames for display on a display as discussed herein. The method includes determining a sampling rate (N) based on a frame rate used for displaying the video data on the display. The sampling rate N is greater than 1. The method further includes, for every N frames of the plurality of frames, processing one or more statistics associated with a frame determine one or more display settings. The method further includes outputting to the display the corresponding N frames of the plurality of frames using the one or more display settings.
