A multi-channel colorimeter has a spectral means which separates light to be measured into components of different wavelengths, a photoelectric converter provided with multiple wavelength channels that receive the separated light to be measured according to the wavelengths to output the corresponding signals at the respective wavelengths, a calculating section that calculates spectral characteristics of the light to be measured based on a composite spectral sensitivity which approximates a predetermined spectral sensitivity by integrating the outputs from the respective wavelength channels multiplied by predetermined weighting factors; and a special weighting factor generator that correctively sets the weighting factors as special weighting factors depending on a spectral intensity of the light to be measured.
