LENS MODULE CAPABLE OF MEASURING A SLOPE OF A LENS BARREL OR A LENS WITH RESPECT TO AN OPTICAL AXIS AND A CAMERA MODULE INCLUDING THE SAME

摘要

PURPOSE: A lens module and a camera module including the same are provided to detect a tilt in advance, thereby minimizing malfunction.;CONSTITUTION: A lens module(100) comprises a lens barrel(110) and a reflection part(120). The lens barrel stores one or more lenses. The outer surface of the lens barrel is corroded. The reflection part is arranged on the lens barrel and reflects light projected from the outside. The reflection part measures a slope of the lens or the lens barrel with respect to an optical axis by comparing an incidence angle and a reflection angle. The reflection part is arranged on a region among the outer surface of the lens barrel which is not corroded.;COPYRIGHT KIPO 2012
