Claim One:
1. An image inspection system for inspecting an image output on a recording medium, the image inspection system comprising: an image forming unit to conduct an image forming operation of a threshold setting image on the recording medium, the threshold setting image prepare-able by adding an artificial defect to an output-target image input to the image forming unit; an image scanner to scan the threshold setting image output on the recording medium to generate a scanned image; an inspection reference image generator to obtain data of the output-target image used by the image forming unit to conduct an image forming operation, and to generate an inspection reference image using the data of the output-target image, the inspection reference image to be used for an inspection of the scanned image; an image inspection unit to determine a defect in the scanned image based on a difference between the inspection reference image and the scanned image; and a threshold determiner to determine a threshold to be compared with the difference between the inspection reference image and the scanned image to determine whether the scanned image includes a defect, wherein the inspection reference image generator generates the inspection reference image of the output-target image for the threshold determination process, wherein the image inspection unit computes the difference between the scanned image, obtained by scanning the threshold setting image, and the inspection reference image for the threshold determination process, wherein the threshold determiner determines a threshold to be compared with the difference between the scanned image and the inspection reference image to determine whether the scanned image includes a defect.
