Abstract
A defect detecting device includes a pixel value correcting section, a block-division processing section, and a defective/non-defective determining section. The pixel value correcting section corrects a pixel value of an inspection-target image, on which detection of a defective area is to be carried out, in such a manner that the defective area of the inspection-target image is emphasized with respect to the other areas of the inspection-target image. The block-division processing section divides, into plural blocks, the inspection-target image with pixel values having been corrected, and obtains a block addition value or a block mean value. The defective/non-defective determining section determines whether or not the defective area is present by carrying out statistical processing to determine whether an outlier of the block addition value or an outlier of the block mean value is present or not.
