Digital controller of novel Voice Coil Motor Actuator for Optical Image Stabilizer
D. H. Yeom, N. J. Park, Sooyong Jung · 2007
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.
