摘要： A camera module includes a lens module, a first frame accommodating the lens module, a second frame accommodating the first frame, and a housing accommodating the second frame. The lens module and the first frame are rotatable about a first axis, with respect to the second frame, perpendicular to an optical axis. The lens module, the first frame, and the second frame are rotatable about a second axis, with respect to the housing, perpendicular to both the optical axis and the first axis. A first ball member is disposed between the first frame and the second frame and elastically supported in a direction of the first axis, and a second ball member is disposed between the second frame and the housing and elastically supported in a direction of the second axis.

摘要： There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.
