Abstract

카메라의 보이스 코일 액츄에이터 구동장치 및 그 방법이 개시된다. 보이스 코일 액츄에이터 구동장치는 보이스 코일 액츄에이터의 공진주파수 및 보이스 코일 액츄에이터에서 나타나는 진동의 감쇠에 기반한 입력 쉐이핑을 수행하여 원시 제어신호로부터 쉐이핑신호를 초기 입력으로 하는 제어신호를 생성하고 입력 쉐이핑이 이루어진 제어신호에 의해 보이스 코일 액츄에이터를 구동한다. 쉐이핑신호는 보이스 코일 액츄에이터의 공진을 제거하기 위한 것이며, 감쇠가 적용되어 신호 변동폭이 점차 감쇠되는 형태를 갖는 멀티-스텝 또는 토글형의 순수 쉐이핑신호이거나, 이러한 순수 쉐이핑신호들을 서로 컨벌루션한 컨벌루션 쉐이핑신호일 수 있다. 이에 따르면, 감쇠를 고려한 입력 쉐이핑 제어에 의해 보이스 코일 액츄에이터의 잔류 진동 억제 성능 및 오토 포커스 성능을 더욱 향상시킬 수 있게 된다.
