PROBLEM TO BE SOLVED: To generate color image data that precisely represent a color of an object to be scanned without the need for a light source or a filter having a spectral energy distribution in matching with a receptor such as human eyes. SOLUTION: The system is provided with a multi-color light source 26 that emits a light in N colors consisting of colors different from nearly red to blue color continuously to an object 12, a photo sensor 44 in response to a light reflected in the object 12 converts the reflected light into a color image data signal set corresponding to the respective N colors, and a color image data processing unit in interlocking with the photo sensor 44 and responding to the generated color image data signal set and converting the color image data signal set corresponding to each of the N colors into equivalent three stimulate values relating to a main stimulus having a prescribed spectral energy distribution.
