Patent ID: 8903231

Claim:
An image stabilizing apparatus comprising: a base; a first frame that is movably coupled to the base in a first direction; a first vibration axis that extends along the first direction to movably support the first frame in the first direction; a first vibration unit that vibrates the first vibration axis; a second frame that is movably coupled to the first frame in a second direction that crosses the first direction; a lens coupled to the second frame; a second vibration axis that is disposed on the first frame and extended along the second direction to movably support the second frame along the second direction; a second vibration unit that vibrates the second vibration axis; a sensing unit that senses a position variation of a sensed frame that is either the first frame or the second frame; a first elastic plate comprising a first connecting portion that is connected to the first frame, and a first pressing portion that is bent from the first connecting portion and contacts and presses the first vibration axis; and a first contact plate that contacts the first connecting portion of the first elastic plate; a magnet disposed on one of the sensed frame and the base; and a magnetism sensing unit that is disposed on the other of the sensed frame and the base to correspond to the magnet and that generates a sensing signal by sensing a change in a magnetic force according to a position of the magnet, wherein: the sensing unit senses position variation of the sensed frame with respect to the base in a sensed frame moving direction; and the magnetism sensing unit comprises two sensors spaced apart.
