Camera module with function of auto-focus and image stabilize
First Claim
1. A camera module comprising:
- a first frame accommodated in a housing, and configured to be movable relative to the housing in an optical axis direction; and
a second frame and a third frame accommodated in the first frame, and configured to be movable in the optical axis direction together with the first frame,wherein the second frame and the third frame are configured to be movable relative to the first frame, andthe third frame is configured to be movable relative to the second frame.

Abstract
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.
