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.
Claims9
A digital camera module, comprising:
- a lens barrel defining a central hollow, and having at least one lens received therein;
- a lens holder defining a central hollow, the lens barrel movably mounted with the lens holder along an axis of the lens holder;
- an image pick-up module being arranged to receive a light from the lens;
- and
- a protective member positioned between and contacting opposing surfaces of the lens barrel and the lens holder, and positioned for preventing dust and/or particle contamination associated with friction between the lens barrel and the lens holder from falling through the central hollow of the lens holder and onto the image pick-up module.
A digital camera module, comprising:
- a lens barrel having an internal thread defined in an inner periphery thereof, and at least one lens received therein;
- a lens holder having an external thread defined in an outer periphery thereof, the external thread engaging with the internal thread of the lens barrel;
- a ring member having a hole in a center thereof for transmitting light therethrough, the ring member positioned between and in contact with opposing surfaces of the lens holder and the lens barrel;
- and
- an image pick-up module being arranged to receive light from the lenses;
- wherein the ring member is positioned for preventing dust and/or particle contamination associated with friction between the lens barrel and the lens holder from falling through the lens holder and onto the image pick-up module.
