Claim:
1. A method of processing high dynamic range video or images comprising: generating a high dynamic range video or image; separating the high dynamic range data for the video or image into separated grayscale and color video or image component data; storing the separated grayscale and color video or image component data in corresponding separate memory spaces; compressing the separately stored color video or image component data; clamping or converting tonal values of the separately stored grayscale video or image component data of the high dynamic range image to generate a grayscale low dynamic range component data; dividing values of the grayscale low dynamic range component data by values of the grayscale high dynamic range component data to obtain fractional component data; compressing the fractional component data; and compressing the grayscale low dynamic range video or image component data.
