1. A person recognition apparatus for recognizing a person by a face image, comprising:
- a storage unit which stores face images of users, and also stores, for a face image having a similar face image, information indicating the existence of the similar face image;
a photographing unit which photographs a face image of a user;
a first face collator which collates the face image photographed by said photographing unit with a plurality of face images stored in said storage unit; and
a second face collator which, in a case where information indicating the existence of a face image similar to the face image collated by said first face collator is stored in said storage unit, performs face image collation by a collating process different from the process performed by said first face collator.

2. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information; a determination unit which determines degrees of collation between a face image to be stored in said storage unit and other face images already stored in said storage unit; a setting unit which sets a threshold value for the face image to be stored in said storage unit, on the basis of those degrees of collation between that face image and the other face images, which are determined by said determination unit; an input unit which inputs identification information of a user; a photographing unit which photographs a face image of the user corresponding to the identification information input by said input unit; and a face collator which performs a collating process for determining whether collation is successful or unsuccessful by checking whether the degree of collation between the face image of the user photographed by said photographing unit and a face image registered in said storage unit and corresponding to the identification information input by said input unit is not less than the threshold value set by said setting unit. - View Dependent Claims (3)

4. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information given to the users; a registration unit which stores in said storage unit another face image of a user whose face image is stored in said storage unit, in one-to-one correspondence with additional information corresponding to each face image of the user and with identification information of the user; an input unit which inputs identification information and additional information of a user; a photographing unit which photographs a face image of the user corresponding to the identification information input by said input unit; and a face collator which collates a face image corresponding to the identification information and additional information input by said input unit with the face image photographed by said photographing unit.

5. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information given to the users; a registration unit which stores in said storage unit another face image of a user whose face image is stored in said storage unit, in one-to-one correspondence with additional information corresponding to each face image of the user and with identification information of the user, and which sets a default face image of face images of a user corresponding to each identification information; an input unit which inputs at least identification information; a photographing unit which photographs a face image of a user corresponding to the identification information input by said input unit; a first face collator which, in a case where additional information is input in addition to the identification information by said input unit, collates a face image corresponding to the identification information and additional information input by said input unit with the face image photographed by said photographing unit; and a second face collator which, in a case where only the identification information is input by said input unit, collates a face image set as a default face image corresponding to the identification information input by said input unit with the face image photographed by said photographing unit.

6. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information given to the users; a registration unit which stores in said storage unit another face image of a user whose face image is stored in said storage unit, in one-to-one correspondence with additional information corresponding to each face image of the user and with identification information of the user; an input unit which inputs identification information of a user and additional information of a face image to be collated; a photographing unit which photographs a face image of the user corresponding to the identification information input by said input unit; a face collator which collates a face image corresponding to the identification information and additional information input by said input unit with the face image photographed by said photographing unit; and an updating unit which, in a case where the collation by said face collator is unsuccessful, updates the face image corresponding to the identification information and additional information stored in said storage unit on the basis of the face image photographed by said photographing unit.

7. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information given to the users; a registration unit which stores in said storage unit another face image of a user whose face image is stored in said storage unit, in one-to-one correspondence with additional information corresponding to each face image of the user and with identification information of the user; an input unit which inputs identification information of a user and additional information of a face image to be collated; a photographing unit which photographs a face image of the user corresponding to the identification information input by said input unit; a face collator which collates a face image corresponding to the identification information and additional information input by said input unit with the face image photographed by said photographing unit; an authenticator which, in a case where the collation by said face collator is unsuccessful, performs authentication to check whether the user photographed by said photographing unit is the user corresponding to the identification information input by said input unit; and an updating unit which, in a case where the user is authenticated by said authenticator, updates the face image corresponding to the identification information and additional information stored in said storage unit, on the basis of the face image photographed by said photographing unit.

8. A person recognition apparatus for recognizing a person by a face image, comprising:
-
a storage unit which stores face images of users in one-to-one correspondence with identification information given to the users; a registration unit which stores in said storage unit another face image of a user whose face image is stored in said storage unit, in one-to-one correspondence with additional information corresponding to each face image of the user and with identification information of the user; an input unit which inputs identification information of a user and additional information of a face image to be collated; a photographing unit which photographs a face image of the user corresponding to the identification information input by said input unit; a face collator which collates a face image corresponding to the identification information and additional information input by said input unit with the face image photographed by said photographing unit; and an additional registration unit which, in a case where the user is authenticated by said authenticator, gives additional information to the face image photographed by said photographing unit and stores the face image in said storage unit in one-to-one correspondence with the identification information.
