Hand vibration correction device

PURPOSE: An image stabilizer is provided to react to a magnetic force change and generates signals corresponding to the same when moving a lens group to a direction intersecting with a direction of the magnetic force change and a gap direction, thereby easily detecting a position of the lens group. CONSTITUTION: An image stabilizer comprises a driving unit (10) and a hall sensor (20). The camera unit includes a magnet (11) installed in an optical axis direction of a camera module (100) and a coil (12). The hall sensor is arranged to be faced the magnet. The thickness of the hall sensor is formed smaller than that of the coil. The hall sensor is arranged inside or outside of the coil. The hall sensor is interposed between the S pole and the N pole of the magnet.
