Red-eye detection device, red-eye detection method, and red-eye detection program
First Claim
1. A red-eye detection device for detecting from an image a red-eye in which at least part of the pupil is displayed red, comprising:
- a red-eye candidate detection section for detecting a red-eye candidate that can be estimated to be said red-eye, by identifying a feature of the pupil that has a region displayed red from among features of said image;
a red-eye pair specification section for specifying said red-eye candidate as a pair of a right red-eye candidate equivalent to a right eye and a left red-eye candidate equivalent to a left eye, using information on a face region obtained from said image; and
an isolated red-eye candidate check section for checking whether an isolated red-eye candidate, detected by said red-eye candidate detection section but not specified as said pair by said red-eye pair specification section, is a true red-eye.

Abstract
A red-eye detection device includes a red-eye candidate detection section, a red-eye pair specification section, and an isolated red-eye candidate check section. The red-eye candidate detection section detects a red-eye candidate that can be estimated to be a red-eye, by identifying a feature of the pupil that has a region displayed red from among features of an image. The red-eye pair specification section specifies the red-eye candidate as a pair of a right red-eye candidate equivalent to a right eye and a left red-eye candidate equivalent to a left eye, using information on a face region obtained from the image. The isolated red-eye candidate check section checks whether an isolated red-eye candidate, detected by the red-eye candidate detection section but not specified as the pair by the red-eye pair specification section, is a true red-eye.

5. A red-eye detection method of detecting from an image a red-eye in which at least part of the pupil is displayed red, comprising:
-
a red-eye candidate detection step of detecting a red-eye candidate that can be estimated to be said red-eye, by identifying a feature of the pupil that has a region displayed red from among features of said image;
a red-eye pair specification step of specifying said red-eye candidate as a pair of a right red-eye candidate equivalent to a right eye and a left red-eye candidate equivalent to a left eye, using information on a face region obtained from said image; and
an isolated red-eye candidate check step of checking whether an isolated red-eye candidate, detected as said red-eye candidate but not specified as said pair, is a true red-eye. - View Dependent Claims (6, 7, 8)

9. A computer-readable storage medium having a red-eye detection program for causing a computer to carry out a process of detecting from an image a red-eye in which at least part of the pupil is displayed red recorded therein, said program causing said computer to carry out:
-
a red-eye candidate detection process of detecting a red-eye candidate that can be estimated to be said red-eye, by identifying a feature of the pupil that has a region displayed red from among features of said image;
a red-eye pair specification process of specifying said red-eye candidate as a pair of a right red-eye candidate equivalent to a right eye and a left red-eye candidate equivalent to a left eye, using information on a face region obtained from said image; and
an isolated red-eye candidate check process of checking whether an isolated red-eye candidate, detected as said red-eye candidate but not specified as said pair, is a true red-eye. - View Dependent Claims (10, 11, 12)
