Camera module and control method thereof

The invention discloses a camera module and a control method thereof. The camera module comprises a base; a lens module which is movably arranged on the base; a limiting assembly which comprises a first limiting part, a second limiting part and a limiting part, and the first limiting part is arranged on the base; a second limiting piece which is arranged on the lens module; and a driving piece, which is connected with the lens module to drive the lens module to move relative to the base so as to drive the lens module to be switched between a locking state and an unlocking state. According to the embodiment of the invention, the limiting assembly is arranged on at least one structure of the lens module and the base, so that the lens module can be kept at a fixed position without being driven by the driving part, abnormal sound generated when the lens module shakes is avoided; meanwhile, the driving part does not need to be continuously electrified to drive the lens module, so that the power consumption can be
