CAMERA MODULE ASSEMBLY, LENS FOCUSING SYSTEM AND METHOD USE OF IT

摘要

A camera module assembly, and a lens focusing system and a lens focusing method using the same are provided to enable a focusing align pin to be inserted into a pin hole to fix a lens strongly during lens focusing, thereby preventing the lens from being out of focus. A camera module assembly(10) includes a tube(11), a lens(12), and a lens cover(13). The lens is installed into the tube to move forward and backward by screws for focusing. The lens cover is installed to the upper side of the lens. A lens hole(13a) is installed in the center of the lens cover. A pin hole(13b) is formed in the circumference of the lens cover to insert a focusing align pin(30). A line trace(13c) is marked to determine a position of the pin hole. A pin hole scale(13d) is formed on the line trace to indicate a direction of the pin hole.
