PERSONAL AUTHENTICATION APPARATUS AND PERSONAL AUTHENTICATION METHOD
First Claim
1. A personal identification apparatus comprising:
- a first determination unit configured to determine a facial expression from a face region of a person included in input image data of a plurality of framesa second determination unit configured to determine a face region of an identical person from a plurality of face regions by comparing information of the plurality of face regions included in the image data of the plurality of frames;
an identification unit configured to identify a person by comparing feature data of a face region of which a facial expression is determined by the first determination unit and feature data for identifying a person stored in advance in a storage unit; and
a registration unit configured to store feature data in the storage unit as feature data corresponding to another facial expression of the identical person when the feature data of the other facial expression of the identical person, which has not been stored yet in the storage unit, is detected from the face region of the person determined and identified as the identical person in image data of a first frame prior to a second frame from the face region included in image data of the second frame.

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.

7. A personal identification method to be executed by a personal identification apparatus which includes:
-
a first determination unit configured to determine a facial expression from a face region of a person included in input image data of a plurality of frames; and a second determination unit configured to determine a face region of an identical person from a plurality of face regions by comparing information of the plurality of face regions included in the image data of the plurality of frames, the method comprising; a step of identifying a person by comparing feature data of a face region of which a facial expression is determined by the first determination unit and feature data for identifying a person stored in advance in a storage unit; and a step of storing feature data in the storage unit as feature data corresponding to another facial expression of the identical person when the feature data of the other facial expression of the identical person, which has not been stored yet in the storage unit, is detected from the face region of the person determined and identified as the identical person in image data of a first frame prior to a second frame from the face region included in image data of the second frame. - View Dependent Claims (9)

8. A camera for capturing an image comprising:
-
a first determination unit configured to determine a facial expression from a face region of a person included in captured image data of a plurality of frames; a second determination unit configured to determine a face region of an identical person from a plurality of face regions by comparing information of the plurality of face regions included in the image data of the plurality of frames; an identification unit configured to identify a person by comparing feature data of a face region of which a facial expression is determined by the first determination unit and feature data for identifying a person stored in advance in a storage unit; and a registration unit configured to store feature data in the storage unit as feature data corresponding to another facial expression of the identical person when the feature data of the other facial expression of the identical person, which has not been stored yet in the storage unit, is detected from the face region of the person determined and identified as the identical person in image data of a first frame prior to a second frame from the face region included in image data of the second frame.
