Patent ID: 8446476

Claim:
An image stabilizer, comprising: a circuit board; a stationary member fixed on the circuit board and defining a first receiving space and a first central axis; a moveable member received in the first receiving space and spaced from the stationary member, the moveable member defining a second central axis coinciding with the first central axis; a driving assembly comprising a first magnetic member fixed to the stationary member and a second magnetic member fixed to the moveable member, the first magnetic member facing the second magnetic member, the driving assembly configured for driving the moveable member to rotate about a first axis and a second axis relative to the stationary member through magnetic interaction between the first magnetic member and the second magnetic member, the second axis being perpendicular to the first axis, the first axis and the second axis being perpendicular to the first central axis; a resilient assembly interconnecting the stationary member and the moveable member, the resilient assembly configured for counter-rotating the moveable member about the first axis and the second axis relative to the stationary member; and a photo-detector fixed on the circuit board and facing the moveable member, the photo-detector configured for detecting movement of the moveable member relative to the stationary member.
