The invention discloses a camera module, a control method and a mobile terminal. The camera module comprises a camera, a driving element, a detection component and a processor, wherein the driving element is connected to the camera and is used for driving a camera to move; the detection component comprises a plurality of circuit branches which are in an open circuit and a conduction element whichis connected to the camera, and the conduction element is used for moving along with the camera and conducting the circuit branches one by one; the processor is electrically connected to the detectioncomponent and is used for acquiring a conduction state of the circuit branch at the camera and determining a position of the camera according to the conduction state of the circuit branch. The camerais connected to the conduction element, so that the conduction element can move along with the camera; subsequently, the movable conduction element can pass through each circuit branch in the detection component and conduct a certain circuit branch. Therefore, the position of the conduction element can be determined according to the conduction state of the circuit branch, so that the position ofthe camera is determined, and whether the camera can move normally or not can be determined in combination with the position of the camera at different moments.
