Abstract
A lens assembly alignment apparatus for a camera lens module is provided. The lens assembly alignment apparatus includes a position alignment apparatus that moves a lens assembly in a direction of an optical axis of the lens assembly and on a plane perpendicular to the optical axis. The apparatus also includes a slant alignment apparatus having first and second rotary axes which extend perpendicular to each other and perpendicular to the optical axis of the lens assembly, respectively. The lens assembly is received in a housing, and the slant alignment apparatus aligns an optical axis of an image sensor, which is mounted in the housing, parallel to the optical axis of the lens assembly by rotating the housing about each of the first and second rotary axes.
