ADAPTING LUMA MAPPING WITH CHROMA SCALING TO 4:4:4 RGB IMAGE CONTENT

At least a method and an apparatus are presented for efficiently encoding or decoding video by adapting Luma mapping with Chroma scaling for 4:4:4 RGB content. For example, a format of an image data of a video to encode is determined to be RGB format; and responsively a RGB mapping is applied to at...

Zusammenfassung:	At least a method and an apparatus are presented for efficiently encoding or decoding video by adapting Luma mapping with Chroma scaling for 4:4:4 RGB content. For example, a format of an image data of a video to encode is determined to be RGB format; and responsively a RGB mapping is applied to at least one of the color components of the image data wherein a RGB mapping adjusts the dynamic range of a color component of an image data in RGB format. Then, the video is encoded based on the at least one RGB mapped color component.
