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: An image capturing unit is provided, including a base, a frame movably connected to the base, a lens holder movably disposed in the frame for receiving a lens, a first magnet, a first coil, a second magnet, and a second coil. When a current is applied to the first coil, a magnetic force is generated between the first magnet and the first coil to move the frame and the lens holder relative to the base. When a current is applied to the second coil, a magnetic force is generated between the second magnet and the second coil to move the lens holder relative to the frame.
