    Abstract: A multiple-lens camera system is provided, including a first lens driving module, a second lens driving module, and a shielding member. The first and second lens driving modules respectively include a frame, a lens holder movably disposed in the frame for holding a lens, a magnetic element disposed on a side of the lens holder and a driving board, wherein the driving board has a first coil corresponding to the magnetic element, to generate a magnetic force for moving the lens holder and the lens relative to the driving board. The shielding member is disposed in the first lens driving module and between the two magnetic elements of the first and second lens driving modules which are adjacent to each other, to suppress magnetic interference between the first and second lens driving modules.

    Abstract: The present invention provides an optical element driving mechanism. The optical element driving mechanism includes a fixed part, a movable part and a driving assembly. The movable part is movably connected to the fixed part. The movable part includes a holder and a holder stopper. The holder carries the optical element. The holder includes a surface, a sidewall and a holder groove. The sidewall faces the optical element. The holder groove is disposed at the junction of the surface and the sidewall. The holder stopper protrudes from the surface along an optical axis of the optical element to limit a range of motion of the holder. The driving assembly drives the movable part to move relative to the fixed part.

    Abstract: An optical system is provided and includes a fixed module, a movable module, a sensing unit and a driving assembly. The fixed module includes a base, and the movable module includes an optical member holder, configured to hold an optical member. The sensing unit is configured to obtain information related to a first rotation angle of the optical member holder when rotating around a first axis relative to the base and a second rotation angle of the optical member holder when rotating around a second axis relative to the base. The driving assembly includes a coil, the coil and the movable module are arranged along an optical axis of the optical member, and the coil is disposed around an opening of the base. The first axis or the second axis is perpendicular to the optical axis.

    Abstract: A driving mechanism is provided, including a base unit, a frame, a holder, a first driving assembly, a sensing magnet, and a magnetic field sensor. The base unit has a polygonal structure. The frame is connected to the base unit. The holder is connected to the frame for holding an optical element, wherein the optical element defines an optical axis. The first driving assembly is disposed on the base unit and the frame, close to a first side of the base unit for driving the holder and the frame to move relative to the base unit along a horizontal direction perpendicular to the optical axis. The sensing magnet is disposed on the holder and close to a second side of the base unit, opposite to the first side. The magnetic field sensor is disposed on the base unit for sensing the sensing magnet.
