Abstract

Hand-phone in the recently released high-end applied to the Camera Module is equipped with the most features Auto Focusing Camera Module and much greater importance of the pixel count is much more precise and reliable AF-powered products are being demanded by consumers. This paper is available now apply the Camera Module VCM (Actuator) for Auto Focusing Lens focal point of the problem location and resolution of positional deviation occurs Module Warranty and stable resolution of the improved structure for Actuator Drive Change the structure VCM is proposed

최근 출시되는 고사양의 Hand-phone에 적용되어진 Camera Module은 대부분 Auto Focusing기능이 탑재되어 있으며 Camera Module의 화소 수가 높아지면서 좀 더 정밀하고 안정적인 AF구동제품이 소비자에 의해 요구되고 있다. 본 논문은 현재 출시되고 있는 Camera Module적용 VCM(Actuator)의 문제점인 Auto Focusing시 Lens 초점위치 및 Module 자세에 따른 해상도편차 발생으로 해상도 보증 및 안정된 Actuator 구동을 위해 개선된 구조의 변경구조 VCM을 제안한다.
