Abstract
An exemplary camera module includes a lens holder (), a lens module (), a position detecting mechanism (), and an image pick-up module (). The lens module includes a lens barrel () and one lens received in the lens barrel. The lens barrel is axially movable received in the lens holder. The position detecting mechanism includes a conductive strip () disposed on outer periphery of the lens barrel along an axial direction, a number of conductive terminals (), a number of electrical sources (), and a processor (). The conductive terminals are securely arranged on an inner periphery of the lens holder parallel to each other. A cathode of each electrical source is electrically connected to a corresponding conductive terminal. The processor is electrically connected with an anode of each electrical source. The image pick-up module is arranged so as to receive the light from the lens module.
