Patent number: 10444530Abstract: 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: February 22, 2016Date of Patent: October 15, 2019Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Sung Ryung Park, Oh Byoung Kwon, Soo Cheol Lim, Byung Woo Kang

Patent number: 9759928Abstract: An optical image stabilizer is provided, in which magnets and coils are arranged such that they oppose each other. The Hall sensors are arranged such that one face of each is opposed to one face of the magnets, respectively. The Hall sensors can detect the location of a group of lenses by generating a corresponding signal in response to a variation in magnetic force following a variation in the gap between magnets depending on the direction in which a group of lenses is driven, and simultaneously, in response to a variation in magnetic force that occurs when the group of lenses is displaced in the direction that intersects the direction of the gap.Type: GrantFiled: September 14, 2015Date of Patent: September 12, 2017Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Soo Cheol Lim, Byung Woo Kang, Sang Min On
