An image processing device that reproduces under a second observation condition an appearance of a color of a subject as perceived under a first observation condition, includes: a characteristic quantity calculation unit that calculates a characteristic quantity related to a state of visual perception adaptation under an observation condition that is at least one observation condition of the first observation condition and the second observation condition, by taking into consideration information related to an illuminating light source used under another observation condition in addition to information related to an illuminating light source used under the one observation condition; and a color conversion unit that executes color conversion to convert the first image data to second image data to be used to reproduce, under the second observation condition, the appearance of the color of the subject as perceived under the first observation condition, based upon the characteristic quantity having been calculated.
