摘要： A spectrum and color reproduction system has a multi-band camera (1), a six-primary-color display (3), and an image converting device (2) which converts a 16-band photographing signal from the multi-band camera (1) into a 6-primary-color display signal of the six-primary-color display (3) by using an input profile of the multi-band camera (1) and an output profile and a color spatial converting profile of the six-primary-color display (3). The input profile and the output profile have information on a corresponding relationship between the respective color signals and one of a spectrum and a spectral reflectance, and the color spatial converting profile has one of a color matching function and an illumination-light spectrum which prescribes a reflection spectrum for the spectral reflectance.

摘要： This invention includes an RGB color camera for photographing an object under photographing illumination light, a simplified spectrophotometer for measuring a photographing illumination light spectrum, and a color correction device for calculating tristimulus value data of the object and converting the data into an input signal to a CRT monitor by using monitor profile data. On the observation side, a CRT monitor and illumination light colorimeter for measuring the tristimulus values of observation illumination light are arranged. A color correction device can perform color reproduction without being influenced by changes in the color perception characteristics of a person such as chromatic adaptation by reproducing a virtual illumination light spectrum having tristimulus values equal to those of the observation illumination light without measuring any observation illumination light spectrum.
