Abstract:
A method of performing luminance/brightness adjustment and gamut mapping to high dynamic range images for a display device includes receiving an input image to analyze an image distribution of the input image, generating a scene information of the input image according to the image distribution, and performing luminance/brightness adjustment and gamut mapping to the input image according to the scene information, to generate an output image corresponding to the input image, wherein the scene information is regarded as dynamic metadata of the input image.
