Abstract

An electronic device is provided. The electronic device includes one or more processors that, while the electronic device is in a locked state, control to detect whether the electronic device is lifted, in response to detecting that the electronic device is lifted, control to activate the display, obtain an image from a camera, detect a face included in the image, and perform authentication of a user based on the face being detected in the image. Based on a result of the authentication, the one or more processors switch a state of the electronic device from the locked state to an unlocked state and display an indicator for indicating that the electronic device is in the unlocked state.

Claims

2. The electronic device as claimed in claim 1, wherein the instructions, when executed by the one or more processors, further cause the one or more processors to maintain the electronic device in the locked state based on the result of the authentication being that the authentication is unsuccessful.

3. The electronic device as claimed in claim 1, wherein the authentication of the user is performed based on the face and at least one eye being detected in the obtained image.

4. The electronic device as claimed in claim 3, wherein the at least one eye comprises an opened eye.

5. A method of an electronic device, the method comprising:

while the electronic device is in a locked state, detecting that the electronic device is lifted;

in response to detecting that the electronic device is lifted while the electronic device is in the locked state and a display of the electronic device is inactivated, activating the display to display a locking screen on the display, obtaining an image from a camera, detecting a face included in the obtained image, and performing an authentication of a user based on the face being detected in the obtained image; and

based on a result of the authentication being successful, switching a state of the electronic device from the locked state to an unlocked state and displaying an indicator for indicating that the electronic device is switching to the unlocked state.

6. The method as claimed in claim 5, further comprising maintaining the electronic device in the locked state based on the result of the authentication being that the authentication is unsuccessful.

7. The method as claimed in claim 5, wherein the authentication of the user is performed based on the face and at least one eye being detected in the obtained image.

8. The method as claimed in claim 7, wherein the at least one eye comprises an opened eye.

9. A non-transitory computer-readable storage medium configured to store one or more computer programs including instructions that, when executed by at least one processor of an electronic device, cause the at least one processor to control for:

while the electronic device is in a locked state, detecting that the electronic device is lifted;

in response to detecting that the electronic device is lifted while the electronic device is in the locked state and a display of the electronic device is inactivated, activating the display to display a locking screen on the display, obtaining an image from a camera, detecting a face included in the obtained image, and performing an authentication of a user based on the face being detected in the obtained image; and

based on a result of the authentication being successful, switching a state of the electronic device from the locked state to an unlocked state and displaying an indicator for indicating that the electronic device is switching to the unlocked state.

10. The non-transitory computer-readable storage medium as claimed in claim 9, wherein the instructions, when executed by the at least one processor, further cause the at least one processor to control for maintaining the electronic device in the locked state based on the result of the authentication being that the authentication is unsuccessful.

11. The non-transitory computer-readable storage medium as claimed in claim 9, wherein the authentication of the user is performed based on the face and at least one eye being detected in the obtained image.

12. The non-transitory computer-readable storage medium as claimed in claim 11, wherein the at least one eye comprises an opened eye.
