This paper proposes a practical methodology for designing an optical image stabilization system controller that consists of a gyro signal filter and feedback controller for a smart phone camera module called miniature camera module. Since the advent of smartphone, miniature camera modules have become much more compact and sophisticated than the modules in the digital single-lens reflex camera. Therefore, a greater consideration on designing controller for the miniature camera module is necessary to obtain higher performance. This paper proposes 1) the OIS system's block diagram connecting the physical part and the controller part and 2) the methodology for designing feedback controller according to the performance index from the block diagram. A linear feedback controller and gyro signal filter are designed using the proposed methodology and its performance is verified via experimentation.
