Abstract

An operator of a monitored instrument is authenticated and a maintenance function for the monitored instrument is released. The head of the authenticated operator is then tracked in a dynamic image and the maintenance function for the monitored instrument is operated when the tracking fails.

Claims

1. A monitoring apparatus, comprising:

an image input unit which generates a dynamic image of a head of an operator of a monitored instrument;

an authentication device which authenticates the operator;

a tracking device which tracks the head of the operator authenticated by the authentication device in the dynamic image; and

a maintenance function control device which releases a maintenance function for the monitored instrument when the authentication device authenticates, and operates the maintenance function for the monitored instrument when the tracking device fails to track the head of the operator authenticated by the authentication device.

2. The monitoring apparatus of claim 1, wherein the authentication device detects a face in the dynamic image to authenticate the operator by using an image of the detected face, and the tracking device tracks the head as a target of the process by the authentication device.

3. The monitoring apparatus of claim 1, wherein the authentication device periodically authenticates the operator while the tracking device tracks the head of the operator in the dynamic image.

4. The monitoring apparatus of claim 1, wherein the maintenance function disables the monitored instrument.

5. The monitoring apparatus of claim 1, wherein the maintenance function restricts access to predetermined data through the monitored instrument.

6. The monitoring apparatus of claim 1, wherein the maintenance function deletes predetermined data when a new operator is authenticated.

7. The monitoring apparatus of claim 1, wherein the maintenance function control device operates the maintenance function when tracking is continuously failed in a predetermined number of frames.

8. The monitoring apparatus of claim 1, wherein the maintenance function control device operates the maintenance function when tracking is continuously failed for a predetermined period of time.

9. The monitoring apparatus of claim 2, further comprising a head detection device which detects the head of the operator prior to the authentication device detecting a face.

10. The monitoring apparatus of claim 1, further comprising a user information storage unit which stores information used to authenticate the operator of the monitored instrument.

11. The monitoring apparatus of claim 1, wherein the image input unit is a digital camera.

12. The monitoring apparatus of claim 1, wherein the monitored instrument comprises a personal computer, a PDA, or a telephone.

13. A monitoring method comprising:

authenticating an operator of a monitored instrument;

releasing a maintenance function for the monitored instrument after the operator is authenticated;

tracking a head of the authenticated operator in a dynamic image; and

operating the maintenance function for the monitored instrument if tracking the head of the authenticated operator fails.

14. The method of claim 13, wherein the operator is authenticated by detecting the operator'"'"'s face in the dynamic image and comparing the operator'"'"'s face to stored data.

15. The method of claim 13, wherein the maintenance function is operated when tracking is continuously failed in a predetermined number of frames.

16. The method of claim 13, wherein the maintenance function is operated when tracking is continuously failed for a predetermined period of time.

17. The method of claim 14, further comprising detecting the operator'"'"'s head prior to detecting the operator'"'"'s face.

18. The method of claim 13, further comprising periodically authenticating the operator while tracking the head of the authenticated operator in the dynamic image.

19. A program which causes an information processing apparatus to execute the steps of:

authenticating an operator of a monitored instrument;

releasing a maintenance function for the monitored instrument when the operator is authenticated;

tracking a head of the authenticated operator in a dynamic image in which the head of the operator of the monitored instrument is taken, when the operator is authenticated; and

operating the maintenance function for the monitored instrument when tracking fails.

20. The method of claim 19, wherein the operator is authenticated by detecting the operator'"'"'s face in the dynamic image and comparing the operator'"'"'s face to stored data.
