A Revision of CIECAM97s for practical applications
Abstract
The CIE 1997 Interim Color Appearance Model (Simple Version), abbreviated
CIECAM97s, was proposed by CIE TC1-34 in 1997 in response to the needs of the
imaging industry for a single, practically-applicable, color appearance model for deviceindependent
color imaging applications. CIECAM97s has been successful in focusing a
large number of researchers in a single direction to implement, evaluate, and suggest
improvements for a single, CIE model. However, CIECAM97s has been less successful
in achieving the goal of being practically applicable. CIECAM97s remains a complex
color appearance model and this complexity seems to be somewhat of a barrier for its
widespread adoption and use. CIE TC8-01 is currently working toward
recommendations for practical application of CIECAM97s. Part of TC8-01’s work is the
consideration and evaluation of potential revisions and simplifications of CIECAM97s.
This paper incorporates several previously proposed enhancements of CIECAM97s and a
few new suggestions into a revised model for the consideration of TC8-01. It is hoped
that this revision will aid in focussing ongoing model tests and perhaps be the starting
point for a new CIE recommendation once sufficient testing and perhaps further
refinements are completed.
