Abstract

Abstract

En 中文
A new optical image stabilizing system for a small mobile device camera is presented. A gyro sensor is used to detect the amount of shaking, and a charge-coupled device (CCD) is shifted to correct the deviated optical axis using a voice coil motor (VCM). Because the VCM is nonlinear, unstable, and time-varying, a new adaptive control technique-multirate fuzzy PID control-is proposed. Our new method is capable of providing improved control with low power consumption. We show clear, stabilized results for a variety of digital photographs taken under conditions of vibration.
