摘要:
A lens moving device is provided. The lens moving device includes: a bobbin; a first driving unit coupled to the bobbin; a second driving unit configured to move the first driving unit through an electromagnetic interaction with the first driving unit; a sensing magnet disposed on one side of the bobbin; a location detection sensor configured to sense a location of the sensing magnet; and a correction magnet disposed on an opposite side of the bobbin.According to the present disclosure, static tilt and dynamic tilt of the bobbin, to which a lens module is to be coupled, may be enhanced by a sensing magnet and a correction magnet which establish magnetic force equilibrium with each other.
