초록

In this study, to compensate trembling of camera caused by vibration of user's hand, 2-axis voice coil actuator of optical image stabilizer (OIS) is suggested. In consideration of actuating performance, volume of OIS and application of hall sensor, one of concept models is selected and it is optimized to maximize the actuating performance. Two types of mechanisms that have the feasibility of moving in 2-axis and the capability of including the optimized EM circuit are proposed. Finally both types are fabricated and then actuating performance of OIS actuator and behavior of hall sensor are verified through the experiment.
