Abstract
An original pupil color of a subject person in an image in which an abnormality such as a red-eye or gold-eye occurs is estimated. Further, 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 is judged. A pupil color estimating device has a skin color of a subject person specified from an inputted image, regardless of whether an abnormality such as a red-eye or gold-eye occurs. This skin color is substituted in an approximate equation based upon a statistical result carried out in advance, and thereby a normal color component of a pupil is estimated from the skin color of the subject person.
