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 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.

摘要： A distance measuring device for measuring the distance to an object is provided, including a light-emitting module, a driving assembly disposed in the light-emitting module, and a light-receiving module. The light-emitting module has a housing, a light source disposed in the housing, a light grating element, and an optical path adjuster. The light source emits a measuring light sequentially through the optical path adjuster and the light grating element along a first axis. The driving assembly can drive the optical path adjuster or the light grating element to move relative to the housing. The light-receiving module receives the measuring light which is reflected by the object to obtain distance information of the object.
