1. A method of operating an inspection system for inspecting a camera module including a control unit, an alignment camera, an alignment stage, and a support socket, the method comprising:
obtaining an image of the camera module by photographing a predetermined region of the camera module above the support socket by the alignment camera;
comparing the image of the camera module with the first pattern image to obtain a position of a first point included in the image of the camera module;
comparing the image of the camera module with a second pattern image to obtain a position of a second point included in the image of the camera module;
obtaining a central position of the position of the first point and the position of the second point;
obtaining an alignment line connecting the position of the first point and the position of the second point;
obtaining a difference vector between the center position and a predetermined reference position;
obtaining a rotation angle between the alignment line and a predetermined reference line; and
driving the alignment stage based on at least one of the difference vector and the rotation angle so that the center position is located at the reference position and the alignment line coincides with a predetermined reference line.
