INSPECTION APPARATUS, INSPECTION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM |
摘要 |
An inspection apparatus inspects a printed product by positioning a reading target image of the printed product relative to a reference image and collating the reading target image with the reference image includes a positioning unit configured to perform positioning processing for the reference image and the reading target image with a first precision, and a detection unit configured to detect an image defect candidate area by collating the reading target image with the reference image, which have been positioned by the positioning unit. The positioning unit newly performs the positioning processing for the reference image and the reading target image in the image defect candidate area with a second precision that is higher than the first precision. The detection unit detects an image defect by collating the reading target image with the reference image in an area having been newly subjected to the positioning processing using the second precision.
