The present invention aims to estimate from an image an original pupil color of a subject person in an image in which an abnormality such as a red-eye or gold-eye occurs. Further, the present invention aims to judge whether an image correction is required or not and to produce an image having a natural pupil color in the image correction by estimating the original pupil color from the image. The present invention provides a pupil color estimating device wherein a skin color of a subject person is specified from an inputted image, regardless of whether an abnormality such as a red-eye or gold-eye occurs, whereupon this skin color is substituted in an approximate equation based upon a statistical result carried out in advance, thereby estimating a normal color component of a pupil from the skin color of the subject person.
