Patent number: 11947132Abstract: 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.Type: GrantFiled: November 19, 2021Date of Patent: April 2, 2024Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Sung Ryung Park, Oh Byoung Kwon, Soo Cheol Lim, Byung Woo Kang
