A display device controlled by a remote control includes an image capture device and a display screen. A remote control of the display device emits light using a light-emitting element, and real-time images of the remote control are captured during the time when the light-emitting element emits light. The captured images are analyzed to calculate a horizontal movement and a vertical movement of the light-emitting element. The display device controls movements of a cursor displayed on the display screen according to horizontal movement and a vertical movement of the light-emitting element. |
