PROBLEM TO BE SOLVED: To provide a video coding pipeline that can accommodate high dynamic range (HDR) and wide color gamut (WCG) content at a fixed bitrate.SOLUTION: The video coding pipeline relies on separate chromaticity-specific and luminance-specific transforms in order to process image content. The image content may be converted into a nearly perceptually uniform color space for coding in constant luminance. Moreover, chromaticity transforms are utilized which reduce coding errors in the chroma components (at the fixed bitrate) by enlarging the code word distribution region for compression.SELECTED DRAWING: Figure 1 |
