1. An image inspection apparatus for inspecting an image output on a recording medium by scanning the output image as a scanned image, the image inspection apparatus comprising: an inspection reference image generator implemented by processing circuitry and configured to obtain an output-target image print data, and to generate an inspection reference image using the output-target image print data, the inspection reference image providing a reference in inspection of a read image; an inspection result acquisition unit implemented by the processing circuitry and configured to acquire a result of a defect determination based on a difference between the generated inspection reference image and the read image; a restriction-on-disclosure process unit implemented by the processing circuitry and configured to change, based on restriction-on-disclosure positional information, which indicates a restricted area in the read image that should be restricted when displayed, a value of a pixel in the restricted area in the read image, when a defect is detected in the read image, to generate a corrected image; and an information transmission unit implemented by the processing circuitry and configured to transmit the corrected image through a network, wherein the restriction-on-disclosure process unit is further configured to maintain the value of the pixel without changing the value of the pixel, when the pixel is included in the restricted area and is determined as the defect.
