CAMERA MODULE CAPABLE OF INCREASING STABILITY BY IMPROVING SHOCK RESISTANCE THROUGH STRUCTURAL SIMPLIFICATION

摘要

PURPOSE: A camera module is provided to prevent pollution of an image sensor due to foreign material drop by minimizing interference of each driving part.;CONSTITUTION: A first lens group(110) is fixed according to an optical axis of an incident light from a subject. A second lens group(120) is formed according to the optical axis, and performs an auto focus control function. A third lens group(130) is moved according to the optical axis. A fourth lens group(140) is moved according to the optical axis. The third lens group and the fourth lens group perform a zoom function. A foreign material preventing part is formed to the fourth lens group, and blocks pollution of the image sensor due to foreign material drop. The first lens group includes a prism. The prism changes an optical path by refracting the incident light. A driving part(150) controls a distance change between the third lens group and the fourth lens group by moving the third lens group and the fourth lens group according to the optical axis direction.;COPYRIGHT KIPO 2010
