Abstract
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.
