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.

An optical member driving system, comprising:
- a first driving mechanism, configured to move a first optical member having a first optical axis, comprising:
- a first base;
- a first frame, movably connected to the first base;
- and
- a first driving assembly, configured to drive the first frame and the first optical member to move relative to the first base, comprising:
- a first coil, disposed on the first frame;
- and
- a first magnetic member, disposed on the first base;
- and
- a second driving mechanism, configured to move a second optical member having a second axis, comprising:
- a second base;
- a second frame, movably connected to the second base;
- and
- a second driving assembly, configured to drive the second frame and the second optical member to move relative to the second base, comprising:
- a second coil, disposed on the second base;
- and
- a second magnetic member, disposed on the second frame, wherein the first axis is different from the second axis.
