Abstract: PURPOSE: A method for detecting a depth direction position of a defect existing on a glass substrate is provided to obtain precisely the depth direction position of the defect regardless of the size, shape and thickness of the defect, thereby capable of obtaining a clear image of the defect. CONSTITUTION: A focus surface of a camera is accorded with a surface of a glass substrate having a defect(S10). The focus surface is moved into the inside of the glass substrate with a constant distance(S20). The camera photographs the defect(S30). A brightness inclination at the boundary between the defect and the background from the image photographed by the camera is calculated and GI(Gradient Indicator) according to the distance moved from the surface of the glass substrate to the focus surface of the camera is calculated(S40). The movement distance is compared with a thickness of the glass substrate(S50). When the movement distance exceeds the thickness of the glass substrate, the distance moved from the surface of the glass substrate corresponding to the maximum value among GI is determined as a depth direction position(S60).
