Design and Simulation of a New Miniature Camera Module Using Voice Coil Motor for Optical Image Stabilization

Abstract

This paper proposes a new design for miniature camera module, which is mainly used to realize optical image stabilization for mobile device with dual-camera. It can compensate the 3 degrees vibration disturbance introduced by the user’s hand-shake. Finite element analysis (FEA) and design of experiments (DOE) are introduced to find the optimum design. Controller design and simulations based on actual hand-shake data collected from the gyro sensors are presented. Simulation results show that the designed camera module can compensate hand-shake up to 50Hz in 3 degrees.
