PROBLEM TO BE SOLVED: To provide a chromaticity instrumentation system for a visible region and an invisible region which utilizes the color values of invisible colors and color display of false-color images, and quantitatively and sufficiently evaluates desired information which is wanted to acquire from a subject sample. SOLUTION: The system 1 has a spectral optical portion 2a which separates light emitted from the subject 10 into its spectral components, a photoelectric conversion portion 2b which performs photoelectric conversion of each separated spectral component and generates an electric signal, an image processing portion 4 which forms a false-color image and calculates numerical values on a colorimetric system for performing color display of the image, and image output portions 5, 6 which output the image and/or the numerical values. The image processing portion multiplies each electric signal by a sensitivity function and generates an image signal, calculates the numerical values by using the signal, multiplies the signal by a matrix M and forms a false-color image. The sensitivity function is determined on the basis of the correlation between the differences in physical or chemical condition among subjects, and differences in waveform produced among spectra of two or more subjects, and M is so determined that a color reproduction error becomes minimum.
