A calculation unit (113), for example, acquires a base vector based on spectral characteristics of a subject to be an identification object with spectral characteristics known form a base vector ROM (114), and spectral characteristics of an image acquisition system including spectral characteristics concerning a color imaging system provided for image acquisition of subjects including the subject to be identification object, and spectral characteristics concerning illumination light used in image acquisition of subjects by the color imaging system, from a system spectral characteristics ROM (115). Then, the calculation unit (113) calculates weighting coefficient concerning the base vector for each wavelength area, from image signal composed of a plurality of color signals obtained in the color imaging system, the base vector and spectral characteristics of the image acquisition system. A normalization unit (116) and a falsely-colored processing unit (117) calculate an output signal as identification result of the subject to be identification object based on those weighting coefficients, to output from a first output unit (118). |
