Abstract: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a CPU. The apparatus may obtain a first indication of an initial histogram for a current frame. The apparatus may also calculate a normalized histogram for the current frame based on a brightness level of the current frame and a total number of pixels in the current frame. Further, the apparatus may select a set of pixel intensity values from a plurality of pixel intensity values for the current frame. The apparatus may also calculate an updated brightness cutoff threshold based on the set of pixel intensity values for the current frame and a set of parameters for a pixel intensity distribution of the current frame. The apparatus may also transmit a second indication of a mapping of the updated brightness cutoff threshold to a backlight value of the current frame.
