Abstract
To mitigate some problems of the pixel color mapping being used in HDR video decoding of the type of SLHDR, a high dynamic range video encoding circuit () is taught, configured to encode a high dynamic range image (IM_HDR) of a first maximum pixel luminance (PB_C), together with a second image (Im_LWRDR) of lower dynamic range and corresponding lower second maximum pixel luminance (PB_C), the second image being functionally encoded as a luma mapping function () for decoders to apply to pixel lumas (Y_PQ) of the high dynamic range image to obtain corresponding pixel lumas (PO) of the second image, Similarly we teach how the same principles can be embodied in a SLHDR-type video decoder.
