Recently, a high-quality image has been obtained by a digital camera because imaging performance was improved. On the other hand, image quality deteriorations due to the vibration has become a problem. In this paper, we propose a three-degree-of-freedom actuator for image stabilizations. The basic structure and operating principle of the actuator are described. Moreover, the dynamic performances under position feedback control are analyzed employing 3-D finite element method and the effectiveness of the actuator is verified.
