providing a glass including an edge region and an inner region;
arranging a light source under the glass;
setting a center position of the light source to correspond to a first point of the glass;
directing light into the glass by using the light source;
first detecting a defect in the edge region of the glass by receiving light passing through the glass by using a detection camera;
adjusting the center position of the light source to correspond to a second point of the glass based on a quality of a result obtained by the first detecting; and
second detecting a defect in the edge region by using the light source with the adjusted center position to obtain a result having a quality different from that obtained by the first detecting.
