    Abstract: A lens unit is provided, including a casing, a carrier, an optical lens, a first driving assembly, and a second driving assembly. The carrier is movably disposed in the casing, and the optical lens is disposed on the carrier. The first and second driving assemblies are provided to drive the carrier and the optical lens respectively to move along a first axis and a second axis relative to the casing. Specifically, when viewed along a direction perpendicular to an optical axis of the lens unit, the first and second driving assemblies do not overlap.

    IPC: G02B27/64

    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 optical driving mechanism is provided, configured to drive an optical element, including a fixed portion, a movable portion, a frame assembly, and a biasing element. The fixed portion includes a base which has a central axis. The movable portion is configured to sustain the optical element and is movable relative to the fixed portion. The frame assembly connects the fixed portion and the movable portion and includes a plurality of string arms, wherein the string arms form at least one V-shaped structure. The biasing element is disposed on the frame assembly and is configured to drive the movable portion to move along a central axis direction relative to the fixed portion, wherein the string arms surround the biasing element and the biasing element is connected to at least one end portion of the V-shaped structure.

    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.
