Title: The New CIE Color Space Based upon the Cone Photoreceptor Fundamentals
Abstract: In 2006 the CIE published a new color space standard based upon the cone photoreceptor fundamentals. This talk will describe those basis functions, a brief history from Newton through Maxwell leading to the new color space, and the additional published norms or correction factors included in the standard for age related changes in optical densities of the lens and other ocular media. The lecture will end with a discussion of multiple primary displays, metamerism, and the future potential for displays to reconstruct power spectra isometrically yielding true color images. (See Brill, M.H., Larimer, J. (2007) Metamerism and Multi-Primary Displays. Information Display, 23/7, 16-21.)
Speaker Background: Dr. Larimer is President of ImageMetrics, LLC. ImageMetrics provides engineering services related to the selection of task specific displays, mitigation of signal capture and processing artifacts such as jaggies, judder, and tone scale banding, and engineering issues related to color. Dr. Larimer has been a university professor and department chairmen, a program director at the National Science Foundation, and recently retired as Senior Scientist from NASA’s Ames Research Center. He has held every office in the Bay Area Chapter of the SID, and served as SID VP for the Americas. He is an Associate Editor of JSID and Co-chair of the IS&T/SID 2008 Color Conference.
