ABSTRACT:
Methods and apparatuses for performing color manipulation using virtual gamuts. In one aspect of the invention, a method to perform color manipulation on a digital processing system includes: performing color manipulation using a virtual gamut of a device if a real gamut of the device is poor quality. When the real gamut of the device is wide, color manipulations are performed using the real gamut of the device. In one example according the this aspect, whether or not the real gamut of the device is poor in quality is determined by comparing an area of the real gamut with a threshold gamut area in a chromaticity diagram. A virtual profile of the device specifies the virtual gamut of the device.
