Abstract: The present invention provides a technique for dynamically improving a defect recognition level, with respect to a defect evaluation technique using an optical defect inspection device. A defect classification method according to the present invention uses two types of images output from the defect inspection device (150) (i.e., a first inspection image generated from a luminance signal sequentially output from a detector (SE) and a second inspection image generated from a difference of signals from an adjacent portion in an area where a defect exists). The first inspection image includes information for discriminating unevenness of a defective shape. Also, while it is difficult to discriminate unevenness of the defective shape by the second inspection image, the second inspection image includes information on a luminance distribution emphasizing a defective portion. An area of the defective portion is extracted from the second inspection image to be applied to the first inspection image, thereby defining an arithmetic processing area, and image processing is performed within the arithmetic processing area to compute a feature amount. Then, images are classified according to a constructed classification standard.
