Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first blade, a transmission assembly, and a driving assembly. The first blade is movable relative to the fixed portion. The transmission assembly is movable relative to the fixed portion. The driving assembly is used for driving the transmission element to move relative to the fixed portion. The transmission element brings the first blade to move relative to the fixed portion when the transmission element is driven by the driving assembly.

Abstract: An optical mechanism is provided for receiving a light that is reflected by a reflecting element. The optical mechanism includes a movable portion, a fixed portion, and a driving module. The movable portion is movable relative to the fixed portion for receiving an optical member that defines an optical axis. The driving module includes a first electromagnetic driving assembly and a second electromagnetic driving assembly for driving the movable portion to move relative to the fixed portion. The optical axis is located between the first electromagnetic driving assembly and second electromagnetic driving assembly when viewed from the optical axis, and the first electromagnetic driving assembly and the second electromagnetic driving assembly are electrically independent from each other.

Abstract: A lens driving device is provided, including a base, a holder, a first driving mechanism disposed on the first side of the base, a second driving mechanism disposed on the second side of the base opposite the first side, and a conductive member disposed on the base. The holder is configured to sustain a lens. The first driving mechanism is configured to force the holder to move along the optical axis of the lens. The second driving mechanism includes a circuit board assembly and a shape memory alloy (SMA) wire assembly configured to force the base to move in the plane perpendicular to the optical axis. The conductive member and the circuit board assembly are connected at an electrical connection point, and the SMA wire assembly is closer to the light-incident end of the lens with respect to the electrical connection point.

Abstract: A camera system including a telephoto lens module is provided. The telephoto lens module includes a first image sensor, a first assembly, and a second assembly. The first assembly includes a first driving mechanism and a reflecting member connected to the first driving mechanism. The first driving mechanism is configured to drive the reflecting member to rotate around a first axis and a second axis. The second assembly is disposed between the first assembly and the first image sensor, including a second driving mechanism and a first lens. The second driving mechanism is configured to drive the first lens to move along a third axis. The first, second, and third axes are not parallel to each other. When light enters the telephoto lens along the first axis, light is reflected by the reflecting member and through the first lens along the third axis to the first image sensor.
