Abstract

Inputs of a plurality of images constituting a group of images of items regarded as non-defective items are previously accepted and stored, and a defect threshold for detecting a defective portion of an inspection object is set based on the plurality of stored images. A defect amount to be compared with a determination threshold for making a non-defective/defective determination on the inspection object is calculated with respect to each of the plurality of stored images based on the set defective threshold, and whether or not each of the calculated defect amounts is an outlier is tested by use of at least one of a parametric technique and a non-parametric technique. Outlier information for specifying an image whose defect amount has been tested to be the outlier is displayed and outputted.
