OPTICAL IMAGE STABILIZER FOR CAMERA LENS ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an optical image stabilizer for a camera lens assembly which can be embedded in a miniaturized, lightweight photography device, such as a micro-digital camera and a mobile communication terminal, and can obtain a clear image even when the photography device is shaken during operation. SOLUTION: The optical image stabilizer for the camera lens assembly includes: a main frame; a drive frame moving on the main frame in at least one direction; a camera device mounted to the drive frame; a pair of driving permanent magnets installed at the one end of one of the main frame and the drive frame; and a pair of coils installed at the other end of one of the main frame and the drive frame and arranged opposite to the driving permanent magnets. The drive frame is moved by the interactions of electromagnetic forces generated when currents are applied to the coils with the magnetic forces of the driving permanent magnets.
