Patent ID: 8218957

Claim:
An image stabilizer, which compensates for an external turbulence caused by hand-shake by moving an imaging unit, the image stabilizer comprising: a first yoke made of a magnetic material; a second yoke made of a magnetic material and comprising a plurality of magnets arranged so as to be rotation-symmetric with respect to a center of the second yoke: a driving frame interposed between the first yoke and the second yoke and movable in a vertical direction, a horizontal direction, and a rotation direction with respect to an optical axis, wherein the imaging unit is mounted in a center of the driving frame; a coil plate connected to a surface of the driving frame facing the first yoke and comprising a plurality of pattern coils arranged at locations corresponding to the plurality of magnets, so that the driving frame is moved by a magnetic interaction between the plurality of pattern coils and the plurality of magnets; and a support unit disposed on a surface of the driving frame facing the second yoke, which supports the driving frame in pitch, yaw and roll directions with respect to the second yoke.
