Paper Abstract

Computer systems thatprocluce color images, usually consist ofcombinations ofhardware and software components that perform different functions, such as capturing, synthesizing or editing images, incorporating images into documents, proofing, and rendering results. Images, and the documents containing them, must be stored temporarily or archivally, and transmitted from component to component. Users will be able to operate such systems more conveniently and flexibility if the parts communicate with each other using a standard interchange format, allowing any conforming module to communicate with any other. This paper discusses the requirements for such an interchange color space, comparing them to some ofthe criteria used to measure traditional color spaces. Any computer interchange space should employ the principles of colorimetry to provide deviceindependence, which is necessary if negotiation between components is to be avoided. Other requirements are accuracy and computational efficiency of transforms to and from device-dependent and internationally standard spaces, ability to represent all visible colors, maximizing the amount of space occupied by the most likely image color gamuts, and robustness against quantization and roundoff errors. This paper proposes ways to measure the performance of color spaces against the defined requirements and applies the tests to several well-known color spaces.
