Abstract

An inspection system extracts feature points from a scan image and from a reference image, performs alignment of the scan image and the reference image based on the extracted feature points, inspects a printed material using the aligned scan and reference images, and performs processing in accordance with a method selected from among a plurality of methods including at least a first method and a second method in a case where the number of the feature points in the reference image is less than a predetermined number. The processing is performed such that, in the case where the number of the feature points in the reference image is less than the predetermined number, the alignment using at least the extracted feature points is performed when the first method is selected, and the inspection is then carried out, whereas the inspection is not carried out when the second method is selected.
