Design of miniaturized optical image stabilization and autofocusing camera module for cellphones

For optical image stabilization (OIS) and autofocusing (AF) camera modules, power efficiency and size are two of the most important characteristics. Therefore, in this paper, we propose a novel voice coil motor (VCM) OIS/AF camera module for cellphones to satisfy the requirements of small size and high power efficiency. The design optimization of the proposed VCM OIS/AF camera module is done using simulations. The results of the simulations show that the proposed VCM OIS camera module has excellent characteristics when compared to a conventional VCM OIS camera module.
