Device for detecting red eye, program therefor, and recording medium storing the program
First Claim
1. 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; and
update means for carrying out an update of the reference data so as to improve a probability of finding an 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.

Abstract
Red-eye area detection accuracy is improved according to a pattern of appearance of red-eye areas generated frequently in an actual photography environment. A red-eye candidate area finding unit finds red-eye candidate areas in a digital photograph image, by using reference data. A display unit displays the image with the red-eye candidate areas having been marked and preliminary corrected. A user can specify an unfound red-eye area and an erroneously specified area by using a specification unit 22. An update unit 24 updates the reference data by learning a characteristic of the unfound red-eye area and the erroneously specified area so that a probability becomes higher regarding detection of an area having a characteristic similar to the unfound red-eye area as a red-eye candidate area while becomes lower regarding detection of an area having a characteristic similar to the erroneously specified area as a red-eye area.
