CUTOFF PREDICTION FOR HISTOGRAM DATA AND BACKLIGHT CONTROL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18069925 titled 'CUTOFF PREDICTION FOR HISTOGRAM DATA AND BACKLIGHT CONTROL
The patent application relates to methods and devices for display processing, specifically involving an apparatus such as a CPU. The apparatus obtains an initial histogram for a current frame and calculates a normalized histogram based on the brightness level and total number of pixels in the frame. It then selects a set of pixel intensity values and calculates an updated brightness cutoff threshold based on these values and parameters for the pixel intensity distribution. Finally, the apparatus transmits a mapping of the updated threshold to a backlight value of the frame.

Original Abstract Submitted
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.
