摘要： 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.

摘要： 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.

摘要： An optical element driving mechanism is configured to receive light. The light is incident to a light-path adjustment element via an incident axis, and travels into the optical element driving mechanism along a first axis, and the incident axis is not parallel to the first axis. The optical element driving mechanism includes a movable portion, a fixed portion, and a driving assembly. The movable portion has a receiving space configured to connect an optical element. The fixed portion includes a base, the movable portion is movable relative to the fixed portion, and the base has a first surface facing the movable portion. The driving assembly is configured to drive the movable portion to move. The movable portion further includes an opening connected to the receiving space, and when viewed along the first axis, the sidewall of the optical element is located between the opening and the first surface.
