Abstract
For extracting a spectral distribution for correcting a result of color measurement under a first observation condition into a result of color measurement under a second observation condition, a first calorimetric value resulting from the color measurement of a sample specimen for evaluation under the first observation condition is acquired, a second calorimetric value resulting from the color measurement of the sample specimen for evaluation under the second observation condition is acquired, and the variable component of the spectral distribution depending on an observation condition as the component of the spectral distribution relating to the sample specimen for evaluation based on the first calorimetric value and the second calorimetric value.
