Abstract

An image processing module can compare a face image of a user with a registered image which is a face image of a normal user, and detect a line of sight from the face image of the user. When the comparison between the face image of the user and the registered image matches at a part other than a line of sight, a control module can determine that an authentication of a user is successful, and start an application corresponding to a direction of the line of sight of the user or display a pre-set screen on a display.

Claims

1. A terminal device comprising:

a display;

an image processing module configured to compare a face image of a user and a registered image, which is a face image of a normal user, and detect a line of sight of the user from the face image of the user; and

a control module configured to, when the comparison between the face image of the user and the registered image matches except for the line of sight, determine that an authentication of the user is successful, and start an application corresponding to a direction of the line of sight of the user, or display a pre-set screen on the display.

2. The terminal device according to claim 1, wherein when the comparison between the face image of the user and the registered image matches at parts except for a line of sight, the control module is configured to release a locked state in which reception of an operation input of a user is rejected.

3. The terminal device according to claim 2, wherein

the display is configured to display at least one selection item, and

the control module is configured to start an application corresponding to the selection item displayed in the direction of the line of sight of the user.

4. The terminal device according to claim 3, wherein when the selection item is not present in the direction of the line of sight of the user, the control module is configured to display the pre-set screen on the display.

5. The terminal device according to claim 4, wherein the pre-set screen includes a standby screen.

6. The terminal device according to claim 2, wherein

the display is configured to display at least one selection item, and

the terminal device further comprising:

a storage module configured to storage a registered image which is a face image of a normal user, and

the image processing module is configured to compare the face image of a user with the registered image at a part except for both eyes, and detect a line of sight of the user from the face image of the user, and

when the comparison between the face image of the user and the registered image matches at the part except for the both eyes, the control module is configured to release a locked state in which reception of an operation input of a user is rejected, and

the control module is configured to start an application corresponding to a detected line of sight of the user.

7. The terminal device according to claim 3, wherein

the display is configured to display a plurality of the selection items, and

the terminal device further comprising:

a storage module configured to storage a plurality of registered images, each of the registered images being a face image of a normal user when the normal user directs a line of sight to a corresponding one of the selection items, and

the image processing module is configured to compare the face image of the user with the registered images, and

when the comparison between the face image of the user and one of the registered images matches, the control module is configured to start an application of the selection item corresponding to the one of the registered images.

8. The terminal device according to claim 7, wherein

when the comparison between the face image of the user and the one of the registered images matches at a part except for both eyes, the control module is configured to release a locked state in which reception of an operation input of a user is rejected, and

when the comparison between the face image of the user and the one of the registered images matches including both eyes, the control module is configured to start an application of the selection item corresponding to the one of the registered images.
