    Abstract: A camera module is provided, disposed in an electronic device, including a base, a holder, an image sensor, a bottom, and a first biasing element. The base is fixed to a casing of the electronic device. The holder is configured to hold an optical lens and connects to the base. The image sensor is supported by the bottom. The base is situated between the holder and the bottom. The first biasing element connects to the bottom and the base, and forces the bottom and the image sensor to move relative to the base.

    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 camera module is provided, including a prism base, a prism driving mechanism, a prism unit, a lens unit, and an image sensor. The lens unit is disposed on the lens driving mechanism. The prism base includes a metal member, at least one first wiring layer, and a first insulation layer disposed between the metal member and the first wiring layer. The prism driving mechanism is electrically connected to the first wiring layer. The prism unit is connected to the prism driving mechanism, and the prism driving mechanism can drive the prism unit to rotate relative to the prism base. The image sensor can catch the light reflected by the prism unit and passing through the lens unit.
