Abstract: An image inspection apparatus for inspecting a scanned image of an output image includes an inspection reference image generator to generate an inspection reference image; an image inspection unit to determine a defect by comparing a difference between the inspection reference image and the scanned image with a threshold; a threshold determiner to determine the threshold; and a defect range determiner to determine a range of defect level of a plurality of artificial defects. Based on a difference computed for a defect selected from the plurality of artificial defects, the threshold determiner determines a threshold to be compared with the difference of the selected defect. The defect range determiner conducts a defect determination for the scanned image at the upper and lower limits for a threshold to determine a range of defect level of the plurality of artificial defects.

Abstract: An inspection apparatus includes a reading device and a processor. The reading device is configured to read printed matter with an image that is printed on a printing medium based on a source image to generate a read image. The processor is configured to generate a reference image based on the source image, determine whether an inspection is to be executed based on a size of the source image and a size of the printing medium, and compare the reference image with the read image to inspect quality of the printed matter in response to a determination that the inspection is to be executed.
