Abstract
A mobile device is provided. The mobile device includes a display screen, an image capture unit, and a processer. The display screen is for displaying information. The image capture unit is for capturing an image. The processer is coupled to the image capture unit to obtain the image. The processer performs a human face detection on the image so as to obtain a human face information from the image, detects a left face area and a right face area of the human face information, and the processer judges that a user stares at the display screen obliquely and performs an eye-protection operation when a ratio of the left face area to the right face area is not equal to a predetermined ratio in a predetermined time.
