Abstract:
The inventors realized that representing HDR content using LDR content and HDR residual is not unproblematic. The invention therefore proposes representing HDR content using LDR content, LDR residual and global illumination data, instead. That is, it is proposed a method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a lower dynamic range depiction of the HDR video content, the method comprising using processing means for encoding one video of the LDR video and a further LDR video extracted from the HDR video independent from the other video of the LDR video and the HDR video and predictive encoding the other video using the one video as reference, and lossless encoding global illumination data further extracted from the HDR video. This has the advantage that prediction is more stable and globally optimal predictors are more easily found.

Claim (Index 4):
Method of  claim 1 , wherein extracting the global illumination data comprises:\n extracting luminance videos from the HDR video and the LDR video, normalizing the luminance videos, pixels-wise computing raw illumination data using the luminance videos and computing the global illumination data by binarizing of the raw illumination data, the method further comprising encoding one or more parameters allowing for de-normalization and/or de-binarization.
