Abstract
The luminances of an image are not only optimized for a particular maximum displayable luminance of a display, but also for a particular amount of light in the viewing environment in which the display is watched. A method of processing an input image to obtain an output image includes receiving a reference luminance mapping function as metadata associated with an input image, calculating an adapted luminance mapping function on the reference luminance mapping function; calculating a control parameter that specifies how much the adapted luminance mapping function deviates from the reference luminance function and is based on a maximum luminance of a display and a black level of the display; and applying the adapted luminance mapping function to at least a portion of the input pixel luminances so as to obtain output luminances for at least a portion of pixels of the output image.
