Abstract
Apparatuses and methods for performing gamut compression. A gamut mapping apparatus of the invention includes a gamut analyzing unit for analyzing the gamut of a source device and the gamut of a target device using a gamut information profile; a gamut compressing unit for mapping original images of the source device within the gamut of the target device by using the analytical information on the gamuts; and a gamut extending unit for increasing the chroma of predetermined images among the compressed original images on the basis of the analytical information on the gamuts and the performance result of the gamut compressing unit.
Claims22
A gamut mapping apparatus, comprising:
- a gamut analyzing unit which analyzes a gamut of a source device and a gamut of a target device based on a gamut information profile to obtain analytical information on the gamuts;
- a gamut compressing unit which compresses original images of the source device within the gamut of the target device using the analytical information;
- and
- a gamut extending unit which increases a chroma of predetermined images among the compressed original images, based on at least one of the analytical information and a performance result of the gamut compressing unit.
A gamut mapping method, comprising:
- analyzing a gamut of a source device and a gamut of a target device by using a gamut information profile;
- compressing original images of the source device within the gamut of the target device using the analytical information on the gamuts if the gamut of the source device is broader than the gamut of the target device;
- and
- increasing a chroma of predetermined images among the compressed original images, based on at least one of the analytical information and a performance result of the gamut compressing unit.
