摘要
The mean color errors of a high-quality digital camera are defined in CIELAB and CIEDE2000 DeltaE 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 DeltaE units and 8.1 CIEDE2000 DeltaE units before corrections. Large color errors are decreased successfully by using three different methods: simple photoeditor, gamma correction, and multiple regression. (C) 2004, Wiley Periodicals, Inc.
