Abstract: An image identification method is used to eliminate accumulated error of operation of a joystick. The joystick has an optical sensor adapted to analyze a movement of a plurality of identification dots disposed on a stick body. The image identification method includes receiving a series of detection images, setting a first identification dot of the plurality of identification dots as being a reference identification dot, and setting a second identification dot of the plurality of identification dos as being the reference identification dot and cancelling the first identification dot as being the reference identification dot when the first identification dot is near a border of the detection image. A position change of the reference identification dot in the series of detection images is used for identifying a control status of the joystick.
