    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.

    IPC: G02B7/02

    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.

    IPC: G02B27/64

    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.
