US Patent 7962023 Image stabilizer

An image stabilizer includes a rotor including a lens assembly, and configured to move perpendicular to an optical axis of light passing through the lens assembly, and a suspension unit configured to support movement of the rotor and to prevent the rotor from moving non-perpendicular to the optical axis of the light passing through the lens assembly. Accordingly, the image stabilizer prevents variance of characteristics of a rotor in a low frequency band according to the position and distortion of phase characteristics in a high frequency band. Therefore, the image stabilizer has consistent operation characteristics regardless of the position, posture, and movement of a person using an image capture device containing the image stabilizer.
