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.
