Dealing with device-dependency of color for device-independent color reproduction

摘要

Abstract: Many people believe that in the future of high fidelity color reproduction, a Device-Independent Color Space (DICS) will be used to represent color image information. Discussions of DICS have focused on what CIE color space is most appropriate as a standard, how to calibrate input devices, and how to characterize output devices. However, the definition of Device-Independent Color has aroused a great deal of confusion in the literature. Does it mean a device-independent definition of color measurement? Does it mean a standardized color space such as a CIE space? Does it mean a method of color transformation such as EFI Color? Does it mean automated (no operator intervention) color matching? Does it mean open system architecture? Does a DICS truly represent color appearance? Does a DICS guarantee device-independency of color? In other words, is the device- dependency of color related only to the color coordinates that are used? If not, where does device-dependency come from? And how does one deal with device-dependency of color in DICS? In this paper, I will address all these issues.!19
