Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
150 words
A red-eye detection device for detecting from an image at least one red-eye in which at least part of a pupil is displayed red, comprising: a red-eye candidate detection section for detecting at least one 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 red-eye candidates detected by said red-eye candidate detection section, 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.
Claim 2
Dependent Claim
150 words
A red-eye detection device for detecting from an image at least one red-eye in which at least part of a pupil is displayed red, comprising: a red-eye candidate detection section for detecting at least one 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 red-eye candidates detected by said red-eye candidate detection section, 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.
Claim 3
Dependent Claim
49 words
The red-eye detection device as set forth in claim 1 , wherein said isolated red-eye candidate check section checks whether said isolated red-eye candidate is a true red-eye, by whether a feature of an eye can be identified from among features of an image containing said isolated red-eye candidate.
Claim 4
Dependent Claim
54 words
The red-eye detection device as set forth in claim 1 , wherein said isolated red-eye candidate check section checks whether said isolated red-eye candidate is a true red-eye, by whether the feature of the pupil having a region displayed red can be re-identified from among features of an image containing said isolated red-eye candidate.
Claim 5
Dependent Claim
36 words
The red-eye detection device as set forth in claim 3 , wherein said re-identification by said isolated red-eye candidate check section is higher in accuracy of identification than said identification by said red-eye candidate detection section.
Claim 6
Dependent Claim
142 words
A red-eye detection method of detecting from an image at least one red-eye in which at least part of a pupil is displayed red, comprising: a red-eye candidate detection step of detecting at least one 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 red-eye candidates detected by said red-eye candidate detection step, 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.
Claim 7
Dependent Claim
142 words
A red-eye detection method of detecting from an image at least one red-eye in which at least part of a pupil is displayed red, comprising: a red-eye candidate detection step of detecting at least one 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 red-eye candidates detected by said red-eye candidate detection step, 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.
