Abstract

An inspection apparatus inspects image data obtained by reading a sheet using a reference image of the image data. The inspection apparatus obtains first image data by reading a sheet having lines printed thereon, obtains second image data from print data of the lines, performs edge correction on the lines included in the second image data by applying a plurality of edge correction parameters being different from each other, and determines an edge correction parameter of the plurality of edge correction parameters that minimizes a difference between a density of the second image data subjected to the edge correction and a density of the first image data. In addition, edge correction is performed on the reference image using the determined edge correction parameter, and image data obtained by reading a sheet of an inspection target using the reference image on which the edge correction has been performed is inspected.
