Claim One:
1. A visual inspection device which compares an image acquired by capturing an inspection object with a group of images of items regarded as non-defective items to make a non-defective/defective determination, the device comprising: an image inputting unit for accepting inputs of a plurality of images constituting a group of images of items regarded as non-defective items, to store these images; a threshold setting unit for setting a defect threshold for detecting a defective portion of an inspection object and a determination threshold for making the non-defective/defective determination based on the plurality of stored images; a defective item image storing unit for storing a defective item image which is an image of an item determined as a defective item; a threshold resetting unit for performing non-defective item learning processing, in a case of acceptance of an input of an image newly acquired by capturing an inspection object, by use of a plurality of stored images including the image whose input has been accepted, to reset at least the defect threshold; a non-defective/defective determination unit for re-detecting a defective portion based on the reset defect threshold, to determine whether or not the stored defective item image is an image of a defective item based on the set determination threshold; and a determination result displaying unit for displaying a non-defective/defective determination result.
