Method, apparatus, and program for detecting red eye
First Claim
1. A red eye detecting method for detecting red eyes, comprising the steps of:
- detecting red eye candidates, by discriminating characteristics inherent to pupils, of which at least a portion is displayed red, from within an image;
detecting faces that include the red eye candidates, by discriminating characteristics inherent to faces, from among characteristics of the image in the vicinities of the red eye candidates;
estimating that the red eye candidates included in the detected faces are red eyes; and
confirming the results of estimation, by judging whether the red eye candidates are the corners of eyes.

Abstract
A process for detecting red eyes within faces included within photographic images and the like includes the steps of: detecting red eye candidates, which may be estimated to be red eyes, by searching the entire image (red eye candidate detecting process); detecting a face that includes the detected red eye candidates, by searching the vicinity of the red eye candidates (face detecting process); estimating which of the red eye candidates are red eyes, by searching within search regions in the vicinities of the red eye candidates at a higher accuracy than that employed during detection of the red eye candidates (red eye estimating process); and confirming whether the results of the red eye estimating process are correct, by judging whether the red eye candidates estimated to be red eyes are the corners of eyes.
