Camera lifting control method and device and mobile terminal

The invention provides a camera lifting control method and device and a mobile terminal. The method is applied to a mobile terminal provided with a lifting camera, the mobile terminal is provided witha Hall sensing module at a preset position, the Hall sensing module comprises an upper Hall sensor and a lower Hall sensor, the lifting camera has magnetism, and the straight line where the upper Hall sensor and the lower Hall sensor are located is parallel to the lifting direction of the lifting camera; the camera lifting control method comprises the steps that when a lifting camera is controlled to ascend and descend, a Hall sensing module is started, and the Hall sensing module is used for collecting the magnetic induction intensity in the moving process of the lifting camera; whether thelifting camera completely ascends or descends or not is judged according to the magnetic induction intensity and preset conditions; and when the lifting camera completely ascends or descends, the stepping motor for driving the
