ResumoAbstract The mean color errors of a high‐quality digital camera are defined in CIELAB and CIEDE2000 Δ E units by using 16 ceramic color samples, whose accurate CIELAB values have been measured by a calibrated spectrophotometer. The bandwidths of CCD's color filters are evaluated by taking photographs of CRT‐display primaries. The lowest mean color errors were 13.1 CIELAB Δ E units and 8.1 CIEDE2000 Δ E units before corrections. Large color errors are decreased successfully by using three different methods: simple photoeditor, gamma correction, and multiple regression. © 2004 Wiley Periodicals, Inc.
