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 lens driving module includes a reflecting element, a base, a frame, a holder, an optical lens, a first electromagnetic driving assembly, and a second electromagnetic driving assembly. The frame is connected to the base, and the holder holds the optical lens and movably connects to the base. The reflecting element reflects light from the outside along a light incident direction to an optical lens along a first direction, wherein the light incident direction is perpendicular to the first direction. The first and second electromagnetic driving assemblies force the holder to move relative to the base, wherein the first electromagnetic driving assembly has a first drive coil, the second electromagnetic driving assembly has a second drive coil, the first and second drive coils have elongated structures extending in a second direction and the first direction respectively, and the first direction is perpendicular to the second direction.

Abstract: An optical system is provided and includes a fixed module, a movable module, a driving coil, an electrical circuit and a magnetic element. The fixed module includes a base and a circuit board, and the movable module includes an optical member holder, configured to hold an optical member. The magnetic element corresponds to the driving coil and is configured to generate an electromagnetic driving force to drive the optical member holder to move relative to the base. The driving coil and the electrical circuit are integrally formed in the circuit board. The driving coil partially overlaps the electrical circuit when viewed along a direction perpendicular to an optical axis of the optical member.
