Claim:
A red-eye detection device comprising: image input reception means for receiving input of a digital photograph image; red-eye candidate area finding means for finding red-eye candidate areas in the digital photograph image by using reference data defining a characteristic of a red-eye area; display means for displaying the digital photograph image so that a user can confirm positions of the red-eye candidate areas that have been found; specifying means for enabling the user to specify a red-eye area that has not been found as one of the red-eye candidate areas, as an unfound red-eye area; update means for carrying out an update of the reference data so as to improve a probability of finding another area having a similar characteristic to the unfound red-eye area as one of the red-eye candidate areas, by learning a characteristic of the unfound red-eye area that has been specified; history storage means for storing history of the update of the reference data by the update means; monitoring means for monitoring a change of detection accuracy based on frequency of specification of the unfound red-eye areas from the specifying means; and resetting means for resetting the reference data to a state at one time in the past stored by the history storage means when the detection accuracy becomes lower than a predetermined threshold.
