Abstract
The present disclosure relates to methods and devices for video processing. In one aspect, the device may obtain a video stream with a plurality of frames. The device can also map, for each frame of the plurality of frames, a first luminance level associated with the frame to a second luminance level based on a transfer function. In some aspects, the transfer function can also include a first function for a first luminance level range and a second function for a second luminance level range, the first function being non-linear and the second function being polynomial. Additionally, the device can indicate, for each frame of the plurality frames, the second luminance level within the video stream. Moreover, the transfer function can include a third function for a third luminance level range, wherein the third function may be between the first and second functions.
