Abstract: 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.

Abstract: An image capturing unit is provided, including a base, a frame movably connected to the base, a lens holder movably disposed in the frame for receiving a lens, a first magnet, a first coil, a second magnet, and a second coil. When a current is applied to the first coil, a magnetic force is generated between the first magnet and the first coil to move the frame and the lens holder relative to the base. When a current is applied to the second coil, a magnetic force is generated between the second magnet and the second coil to move the lens holder relative to the frame.

Abstract: The present invention provides a VCA-based lens driving device. By way of giving an improved OIS coil structure, a magnetic induction element used to sense movement of magnets atop which maybe cause from a user's hand shaking can be placed as far away from OIS coils as possible. The impact of the magnet field of the OIS coil on the magnetic induction element is thus reduced. In one embodiment, the OIS coil is down-sized to reduce the influence of the OIS coil on the magnetic induction element placed beside it. In another embodiment, the OIS coil has a one-sided indention and the magnetic induction element is placed below/or beside the indention of the OIS coil.
