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: An optical element driving mechanism is provided and includes a movable portion and a fixed portion. The movable portion includes a carrier for carrying an optical member with a first optical axis. The fixed portion has a top surface, a first side surface and a second side surface. The top surface extends in a direction that is parallel to the first optical axis. The first side surface and the second side surface extend in a direction that is not parallel to the first optical axis from the edge of the top surface and face different sides of the optical member. The shortest distance between the optical member and the first side surface is shorter than the shortest distance between the optical member and the second side surface. The optical element driving mechanism includes a noise-reducing structure configured to avoid a noise entering a photosensitive member.
