US Patent 10338403 Lens driving mechanism and method for controlling the same

A lens driving mechanism is provided. The lens driving mechanism is configured to drive an optical lens, including a holder, a base, a first elastic element, and a first biasing element. The optical lens is disposed in a receiving space of the holder. The base has a central axis, and the holder is movable relative to the base. The first elastic element is connected to the holder and the base. The first biasing element exerts a force on the holder so that an optical axis of the optical lens has an angular displacement relative to the central axis.
