PERSONAL AUTHENTICATION APPARATUS AND PERSONAL AUTHENTICATION METHOD
First Claim
1. A personal authentication apparatus comprising:
- an input unit configured to input image data;
a face detection unit configured to detect a face region of a person included in the image data input by said input unit, and to detect feature data from the detected face region;
a facial expression determination unit configured to determine a facial expression from the face region detected by said face detection unit;
a selection unit configured to select feature data corresponding to the facial expression determined by said facial expression determination unit, the feature data used to authenticate a person in correspondence with respective facial expressions of a plurality of faces are obtained from and stored in an external database; and
an authentication unit configured to authenticate a person by comparing the feature data of the face region detected by said face detection unit, and the feature data selected by said selection unit.

Abstract
A personal authentication apparatus comprises an input unit configured to input image data; a face detection unit configured to detect a face region of a person included in the image data input by the input unit, and to detect feature data from the detected face region; a facial expression determination unit configured to determine a facial expression from the face region detected by the face detection unit; a storage unit configured to store feature data used to authenticate a person in correspondence with respective facial expressions of a plurality of faces; a selection unit configured to select feature data corresponding to the facial expression determined by the facial expression determination unit from the storage unit; and an authentication unit configured to authenticate a person by comparing the feature data of the face region detected by the face detection unit, and the feature data selected by the selection unit.

4. A personal authentication method to be executed by a personal authentication apparatus which includes:
-
an input unit configured to input image data; a face detection unit configured to detect a face region of a person included in the image data input by the input unit, and to detect feature data from the detected face region; and a facial expression determination unit configured to determine a facial expression from the face region detected by the face detection unit, the method comprising; a selection step of selecting feature data corresponding to the facial expression determined by the facial expression determination unit, wherein the feature data used to authenticate a person in correspondence with respective facial expressions of a plurality of faces are obtained from and stored in an external database; and an authentication step of authenticating a person by comparing the feature data of the face region detected by the face detection unit, and the feature data selected in the selection step.
