Abstract:
A method for tone mapping includes configuring, by at least one processor, at least one tone mapping function based on a measure of a distribution of luminance values within video data. The measure of a distribution of luminance values represents a luminance level at which a predetermined percentage of pixels of the video data have luminance values satisfying a threshold condition. The method includes generating a tone mapped video by applying the at least one configured tone mapping function to the video data.
