Abstract
Chroma correction of inverse gamut mapping (IGM) for standard dynamic range (SDR) to high dynamic range (HDR) image conversion includes: converting R,G,B color components in the RGB color format of a pixel of an image to an intensity component (I) and chroma components (Ct and Cp) of an ICtCp color format, wherein the R,G,B color components represent red, green, and blue colors; applying an intensity transformation operation on the intensity component (I) of the pixel; executing a chroma correction operation on the transformed intensity component (I) and the chroma components (Ct and Cp) of the pixel; and converting the intensity component (I) and the chroma components (Ct and Cp) of the pixel back to the RGB color format.
