IMAGE INSPECTING DEVICE AND IMAGE INSPECTING PROGRAM

摘要

An image inspecting device (10) automatically extracts points of difference between first image data and second image data by comparing the first image data, created as data representing a reference image serving as an inspection reference, and the second image data, created as data representing an inspection image serving as an inspection target. The image inspecting device (10) comprises: a storage means which stores the reference image and the inspection image; an image processing means which performs an image superimposing process by making at least a portion of the stored reference image and at least a portion of the inspection image correspond at the pixel level as the first and second image data; a difference detecting means which detects differences between the two sets of image data by comparing the superimposed first and second image data; an image generating means which compares a plurality of threshold values with the differences to generate error-displaying image data for each threshold value; and image inspecting means which performs an image inspecting process using the generated error-displaying image data for each threshold value.
