    Abstract: A lens driving module includes a base, a frame fixedly connected to the base, and a holder configured to connect an optical lens. The holder is movable relative to the base. The lens driving module also includes a reflecting element configured to reflect light from a light incident direction to a first direction. The first direction is perpendicular to the light incident direction, and the first direction is parallel to an optical axis of the optical lens. The lens driving module further includes a first electromagnetic driving assembly configured to force the holder to move along the first direction relative to the base. The lens driving module has multiple recesses formed on the base and arranged along the first direction. The lens driving module includes multiple the rolling elements disposed on the recesses, and the holder is moved relative to the base via the rolling elements.

    Abstract: An optical system is provided. The optical system includes a first optical module and a second optical module. The first optical module is used for connected to a first optical element. The second optical module is used for connected to a second optical element. A light enters the first optical module along an incident direction, and the light is adjusted by the first optical module to enter the second optical module along a first direction. The incident direction is not parallel with the first direction.

    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.

    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.
