Digital controller of novel Voice Coil Motor Actuator for Optical Image Stabilizer

This paper deals with an OIS (optical image stabilization) system by means of actuating CCD (change charged device). The purpose of OIS is to obtain a clear image through compensating the vibration of cameras or camcorders. Newly developed VCMA (voice coil motor actuator) is used for actuating CCD, and a low cost and high performance control system is implemented by a modified lag-lead compensation method.
