<P>PROBLEM TO BE SOLVED: To solve the following problem: in order to estimate a spectral reflectance of an object using a conventional color image processor, information about a spectral sensitivity of a color image signal input device and about an illumination light spectrum in image acquisition is required however it is difficult to accurately measure a spectral sensitivity characteristic and data being provided are not sufficient due to individual difference or aging. <P>SOLUTION: A color image processor is characterized in that image data photographed with a camera is written in a memory card and also information about a designation chart photographed concurrently with the image data and about an object is written in the memory card as head information, and the image data is converted into a spectral reflectance of the object by utilizing the information about the designation chart read from the memory card. <P>COPYRIGHT: (C)2008,JPO&INPIT |
