Abstract
A digital camera module (100) includes a lens barrel (20), a lens holder (22), an image pick-up module (26), and a protective member. The lens barrel defines a central hollow, and has at least one lens (202) received therein. The lens holder defines a central hollow. The lens barrel is movably received in the lens holder along an axis of the lens holder. The image pick-up module is arranged to receive light from the lenses. The protective member is configured for preventing dust and/or particle contamination associated with a relative movement of the lens barrel and the lens holder falling onto the image pick-up module.
