Abstract
A method, apparatus, and non-transitory computer readable medium for video tone mapping. The method includes receiving the video and metadata at least partially representative of a global tone mapping function. The method further includes determining the global tone mapping function based at least on the metadata and a characteristic of the display and generating a tone mapped video by applying the global tone mapping function to the video and using the peak luminance value of the display in the application of the global tone mapping function.
