Lens driving apparatus and camera module including function of shaking compensation

摘要

Disclosed is a camera module. The camera module includes a lens barrel disposed in a housing to receive a lens; and a driving unit moving the lens barrel relative to the housing, wherein the driving unit comprises: a first driving unit in the lens barrel; and a second driving unit in the housing, and wherein the lens barrel comprises a central area on which the lens is disposed; and a peripheral area surrounding the central area, in which the first driving unit is disposed in the peripheral area. The camera module includes a lens barrel disposed in a housing to receive a lens; and a plurality of driving units moving the lens barrel relative to the housing, wherein a first direction is defined perpendicularly to an optical axis of the lens, a second direction is defined perpendicularly to the optical axis of the lens and the first direction, and the driving units including coils and moving the lens barrels in the same direction along the first direction or the second direction have coil winding directions corresponding to each other.
