摘要： Provided herein is a control method of an electronic device. A gesture is detecting and a plurality of images of a user are photographed, if the gesture substantially corresponds to a predetermined gesture. A predetermined function is performed, if the change detected in the images is less than a predetermined threshold during a predetermined time period.
