A camera module capable of aligning an optical axis is disclosed. The camera module includes an imaging unit which captures an image for optical axis alignment; and a control unit which selects distortion feature point coordinates with the minimum error by comparing reference feature point coordinates with distortion feature point coordinates belonging to a predetermined pixel area of an image sensor among distortion feature point coordinates of the distorted image for optical axis alignment obtained by the image capture, determines the selected distortion feature point coordinates as center coordinates by quantizing the selected distortion feature point coordinates, and aligns the optical axis using the determined center coordinates as an offset value for optical axis compensation. Accordingly, optical alignment can be performed by a software mode with respect to a camera module completed by assembling an optical system without considering optical axis alignment. |
