Abstract

A multifunction printer captures an image, extracts face data of each person from the captured image, verifies whether each person has been authenticated based on the extracted face data, transmits face data of a person that cannot be verified to have been authenticated to an external apparatus, requests authentication of that person, temporarily stores face data of each authenticated person, collates extracted face data of each person with stored face data, and verifies whether each person has been authenticated.

Claims

1. An information processing apparatus that permits a user to use thereof through authentication, comprising:

an image capturing unit;

an extracting unit configured to extract feature information of each person recognized based on images captured by the image capturing unit;

a temporary storing unit configured to temporarily store feature information of one or more persons authenticated by an external apparatus, the external apparatus storing feature information of one or more persons to be authenticated;

a verification unit configured to verify whether each person has been authenticated based on feature information stored in the temporary storing unit and feature information of each person extracted by the extracting unit; and

an authentication unit configured to transmit feature information of a person who cannot be verified as authenticated to the external apparatus and request authentication of the person;

wherein feature information of an authenticated person authenticated by an external apparatus is deleted from the temporary storing unit after the authenticated person left from an area, the extracting unit being able to extract feature information of each person in the area.

2. The information processing apparatus according to claim 1, further comprising a first detection unit configured to detect a change in person recognized from the captured image,

wherein if a change in person is detected by the first detection unit, the extracting unit extracts each feature information of each person recognized from the captured image.

3. The information processing apparatus according to claim 2, wherein the change in person recognized from the captured image is a change in the number of persons recognized from the captured image.

4. The information processing apparatus according to claim 1, further comprising a first deletion unit configured to delete, from the temporary storing unit, feature information that cannot be collated with feature information of each person extracted by the extracting unit from among feature information stored in the temporary storing unit.

5. The information processing apparatus according to claim 4, wherein the first deletion unit deletes, from the temporary storing unit, feature information that has been stored in the temporary storing unit for a time exceeding a certain period of time.

6. The information processing apparatus according to claim 4, further comprising:

an acquisition unit configured to acquire user information of each person authenticated by the authentication unit;

a holding unit configured to hold the user information of each person acquired by the acquisition unit; and

a second deletion unit configured to delete, from the holding unit, user information of a person corresponding to feature information to be deleted if feature information stored in the temporary storing unit is deleted by the first deletion unit.

7. The information processing apparatus according to claim 6, wherein the user information includes at least one of information for customizing a manipulation unit, connection information to a location where personal data is stored, or a personal address book.

8. The information processing apparatus according to claim 6, wherein the acquisition unit acquires the user information from the temporary storing unit or from a source external to the information processing apparatus.

9. The information processing apparatus according to claim 6, further comprising:

a second detection unit configured to detect a portrait image in a specific region of the captured image of the image capturing unit;

a determination unit configured to determine a person corresponding to the portrait image as a priority user based on the detected portrait image if a portrait image is detected in the specific region by the second detection unit; and

a setting unit configured to acquire user information of the priority user from the holding unit and set the information processing apparatus based on the user information.

10. The information processing apparatus according to claim 9, wherein the determination unit measures a distance between a person corresponding to the portrait image and the information processing apparatus based on a size of the portrait image in the specific region and

if the measured distance is shorter than a predetermined distance, determines the person as a priority user.

11. The information processing apparatus according to claim 9, wherein the portrait image is an image of a face.

12. The information processing apparatus according to claim 9, wherein the setting unit releases the setting based on the user information of the priority user when the portrait image is no longer detected from the specific region by the second detection unit.

13. The information processing apparatus according to claim 9, wherein the first deletion unit deletes the feature information of the priority user from the temporary storing unit when an instruction indicating that use of the information processing apparatus is completed is input.

14. The information processing apparatus according to claim 1, wherein the feature information of a person is information indicating a feature of a person'"'"'s face.

15. The information processing apparatus according to claim 1, wherein the information processing apparatus is an image processing apparatus.

16. A method for controlling an information processing apparatus that permits a user to use thereof through authentication, the method comprising:

capturing an image;

extracting feature information of each person recognized based on the captured image;

temporarily storing feature information of one or more persons authenticated by an external apparatus in a temporary storing unit, the external apparatus storing feature information of one or more persons to be authenticated;

verifying whether each person has been authenticated based on feature information stored in the temporary storing unit and extracted feature information of each person; and

transmitting feature information of a person who cannot be verified as authenticated to the external apparatus; and

requesting authentication of the person;

wherein feature information of an authenticated person authenticated by an external apparatus is deleted from the temporary storing unit after the authenticated person left from an area, the information processing apparatus being able to extract feature information of each person in the area.

17. A non-transitory computer-readable storage medium storing computer executable instructions that cause a computer to execute a method for controlling an information processing apparatus that permits a user to use thereof through authentication, the method comprising:

capturing an image;

extracting feature information of each person recognized based on the captured image;

temporarily storing feature information of one or more persons authenticated by an external apparatus in a temporary storing unit, the external apparatus storing feature information of one or more persons to be authenticated;

verifying whether each person has been authenticated based on feature information stored in the temporary storing unit and extracted feature information of each person; and

transmitting feature information of a person who cannot be verified as authenticated to the external apparatus; and

requesting authentication of the person;

wherein

feature information of an authenticated person authenticated by an external apparatus is deleted from the temporary storing unit after the authenticated person left from an area, the information processing apparatus being able to extract feature information of each person in the area.
