Abstract
The invention creates improved images for various viewing environment light levels. The invention process an input image with an input luminance dynamic range with an input maximum luminance using a processing system. The input image has metadata which specifies a reference luminance mapping function. The output image has an adjusted maximum luminance determined by subtracting a user correction value from an output maximum luminance. The luminances of the input image are processed using an adapted luminance mapping function. The adapted luminance mapping function is based on the adjusted maximum luminance value and the reference luminance mapping function.
