Abstract
Tone and/or gamut mapping apparatus and methods may be applied to map color values in image data for display on a particular display or other downstream device. A mapping algorithm may be selected based on location and/or color coordinates for pixel data being mapped. The apparatus and methods may be configured to map color coordinates differently depending on whether or not a pixel corresponds to a light source in an image and/or has special or reserved color values.
