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 system is provided and includes a light-sensing element, at least one optical lens, a reflecting unit and a first driving assembly. The reflecting unit includes a reflecting surface, configured to receive an incident light and to reflect a reflecting light. The reflecting light travels through the optical lens into the light-sensing element. The first driving assembly is configured to control the reflecting unit to move along a first axis direction, so as to adjust a focus position of the reflecting light on the light-sensing element.

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 substantially perpendicular to the first direction. The first and second electromagnetic driving assemblies are configured to force the holder and the optical lens to move relative to the base, wherein the first and second electromagnetic driving assemblies are situated in different positions in the light incident direction.

Abstract: A lens module comprises a housing, a lens holder movably accommodated in the housing and an optical image stabilization device (OIS device). The OIS device is configured to generate a driving force according to the movement of the lens holder so as to stabilize the lens holder. The OIS device of the lens module further comprises a substrate and a plurality of driving coils received in the substrate by means of embedment so that the OIS device occupies a smaller proportion of space in the lens module and thereby to keep the lens module compact.
