Abstract
This invention enables a family of HDR gradings for various displays on which the HDR image may need to be shown. The HDR color gradings are obtained by calculating resultant colors of pixels of an output image for a display with a display peak brightness. The calculation begins from input colors of pixels of an input image, the input image having a maximum luma code corresponding to a first image peak brightness. The first image peak brightness is different from the display peak brightness. The color transformation determination determines a color transformation from color processing specification data. The color processing specification data has at least one tone mapping function for at least a range of pixel luminances received via a metadata input.
