Camera module

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.

Description

[0001] This application claims No. 10-2014-0043833 filed with the Korean Intellectual Property Office on April 11, 2014, No. 10-2014-0066563 filed with the Korean Intellectual Property Office on May 30, 2014, and Priority and benefit of Korean Patent Application No. 10-2014-0128689 filed with the Korean Intellectual Property Office on September 25, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Some embodiments of the present disclosure relate to a camera module. Background technique [0003] Recently, ultra-compact camera modules with a high degree of functionality have been adopted in mobile communication terminals such as tablet and notebook computers or portable computers, and portable mobile phones such as smartphones. [0004] As mobile communication terminals are miniaturized, image quality may degrade since the influence of hand shake may be noticeable when capturing images. Therefore, in order to obtain clear i...
