Abstract
A method maps a color specified using a smaller color gamut to a larger color gamut. Under that method, a map in a chromaticity diagram is constructed that provides a direction and a magnitude for a unit change in chroma for a specified pixel value in the chromaticity diagram. Using the magnitude and direction in the map, the specified color is mapped to a new pixel value corresponding to a predetermined shift in chromaticity. Preferably, the new pixel value preserves the hue of the specified color, and its luminance related to that of the specified color. Also, the new pixel value preferably has a greater color saturation than the specified pixel value.
