1. An electronic device comprising:
- an image capturing unit; and
a processor for controlling the image capturing unit to periodically capture an image in front of the electronic device, and analyzing the captured image to determine whether a user is using the electronic device, and further controlling the electronic device to be in a working state if a user is using the electronic device;
wherein the processor compares the captured image with a pre-stored image to determine whether a difference between the captured image and the pre-stored image matches a preset value, and determine that a user is using the electronic device if the difference matches the preset value;
wherein the pre-stored image is an image of a human face without eyes, if the difference matches the preset value, the processor determines that the captured image comprises eyes, and determine that a user is using the electronic device.

Abstract
An electronic device includes an image capturing unit and a processor. The processor controls the image capturing unit to periodically capture an image in front of the electronic device, and analyzes the captured image to determine whether a user is using the electronic device, and further controls the electronic device to be in a working state if a user is using the electronic device. A method for controlling an electronic device is also provided.

8. A method for controlling an electronic device, the electronic device comprising an image capturing module, the method comprising:
-
controlling the image capturing module to periodically capture an image in front of the electronic device; analyzing the captured image to determine whether a user is using the electronic device; and controlling the electronic device to be in a working state if a user is using the electronic device; wherein the step of analyzing the captured image to determine whether a user is using the electronic device comprises; comparing the captured image with a pre-stored image to determine whether a difference between the captured image and the pre-stored image matches a preset value; and determining that a user is using the electronic device if the difference matches the preset value; and wherein the pre-stored image is an image of a human face without eyes, if the difference matches the preset value, the captured image is determined to comprise eyes, and a user is determined to be using the electronic device. - View Dependent Claims (9, 10, 11)
