摘要：
An image characterized by an original image gamut is received in an imaging device characterized by a device gamut. The original image gamut is enhanced to a first set of modified color values that occupy a greater fraction of the device gamut than the original image gamut. The modified color values of each pixel are mapped to new color values within the device gamut.
