Optical image stabilizer for camera lens assembly
First Claim
1. An optical image stabilizer for a camera lens assembly, comprising:
- a housing;
a board that has an image sensor on a top surface thereof and disposed movably in the housing, the board and the housing being spaced apart from each other;
at least one magnetic body disposed between the board and the housing, the magnetic body providing a magnetic force acting in a direction along which the board is closely contacted to inner surface of the housing;
at least three balls interposed between the board and the inner surface of the housing for maintaining the board in such a state that it is spaced apart from the housing; and
a driving unit for correcting the position of the image sensor by moving the board according to trembling of user'"'"'s hands.

Abstract
An optical image stabilizer for a camera lens assembly includes: a board that has an image sensor on a top surface thereof and disposed movably in the housing, the board and the housing being spaced apart from each other; at least one magnetic body disposed between the board and the housing, the magnetic body providing a magnetic force acting in a direction along which the board is closely contacted to inner surface of the housing; at least three balls interposed between the board and the inner surface of the housing for maintaining the board in such a state that it is spaced apart from the housing; and a driving unit for correcting the position of the image sensor by moving the board according to the degrees of trembling of user'"'"'s hands. In the optical image stabilizer for a camera lens assembly, the driving unit for driving the board, on which an image sensor is mounted, is present substantially on the same surface as the board itself. As a result, the optical image stabilizer can downsize a product equipped with a camera lens assembly and can improve the reliability of the product.
