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.
