Abstract
Systems, apparatus and methods are provided to map a video range of image data to the video range of a display. Embodiments apply a weighted combination of values in input image data streams to generate image data having a range which matches the display capabilities. The weighted combination may be determined based on relative capabilities of the display and input image data. The video range of the image data and display may be a range of colors (gamut) and/or luminance (dynamic range).
