An image inspection device includes a processor coupled to a sensor. The processor reads, using the sensor, an image formed on a recording material by an image forming device and creates a read image; causes an analysis to detect an abnormality in the read image and creates an analysis result; and creates a normal image file including the read image in which the abnormality has not been detected based on the analysis result.

An image inspection device detects an abnormality of a formed image by comparing imaged data obtained by imaging the formed image with original image data of the formed image. The image inspection device includes a hardware processor that: adjusts the original image data to reduce sharpness of the original image data; and detects the abnormality by comparing the adjusted original image data with the obtained imaged data. The hardware processor partly restricts the reduction of the sharpness.

An inspection image is assumed to contain many abnormalities when a reference image and an inspection image are misaligned. It has been impossible to determine whether the abnormalities are attributed to the inspection image. An image inspecting apparatus includes: a print alignment portion that aligns a print position of a reference image with a print position of an inspection image; an abnormality detector that detects an abnormality in the inspection image based on a difference between the reference image and the inspection image after print positions are aligned; and a print alignment result evaluator that evaluates a print position alignment result from aligning a print position of the reference image with a print position of the inspection image including an abnormality detected based on dispersion of the difference included in an evaluation region around an edge calculated from a printout image included in the reference image.

An inspection apparatus for inspecting printed matter on which an image is formed, includes: a region extractor that extracts a first region, in which a character is formed, and a second region, in which the character is not formed, with reference to image forming image data used to form the image; and a defect detector that detects a defect in the first region and a defect in the second region in read image data obtained by reading the printed matter on which the image is formed by the image forming image data, wherein the defect detector includes: a first region defect detector that detects loss of a dot in the first region in the read image data; and a second region defect detector that detects presence of a dot with a density equal to or greater than a predetermined density in the second region in the read image data.

Inspection apparatus and inspection program

An image forming apparatus includes an image forming unit, an image reading unit, an image inspecting unit and a history generating unit. The image forming unit forms an image on a sheet. The image reading unit reads a sheet face on which the image is formed, thereby generating a scan image. The image inspecting unit compares the generated scan image with a normal image to detect an error in the scan image. When the image inspecting unit detects the error, the history generating unit generates detection information on the detected error and embeds the generated detection information in the scan image, thereby generating a history image.
