Abstract

본 발명은 카메라 모듈의 렌즈를 이동시키는 보이스 코일 모터(Voice Coil Motor:이하 VCM이라 함)의 구동제어에 관한 것으로, 특히 렌즈 초기 구동 혹은 랜딩(landing) 시에 소음을 저감시키고 이동시간을 단축시킬 수 있는 VCM 구동제어방법에 관한 것으로, 카메라 동작 명령에 응답하여 미리 설정된 제1변곡점까지 제1기울기를 가지고 선형 증가하는 전류를 상기 VCM에 인가하는 단계와, 상기 변곡점에서 인피니트 포지션까지 상기 제1기울기보다 작은 제2기울기를 가지고 선형 증가하는 전류를 상기 VCM에 인가하여 렌즈를 인피니트 포지션으로 이동시키는 단계를 포함함을 특징으로 한다.
