IMAGE INSPECTION APPARATUS, IMAGE FORMING SYSTEM, AND IMAGE INSPECTION METHOD

摘要

An image inspection apparatus includes a first-image obtaining unit, a scanned-image obtaining unit, a second-image obtaining unit, first and second registration units, a combining unit, and an inspection unit. The first-image obtaining unit obtains a first image generated by scanning a sheet on which a predetermined image has been printed. The scanned-image obtaining unit obtains a scanned image generated by scanning a printed matter produced by printing a second image additionally on the sheet. The second-image obtaining unit obtains the second image. The first registration unit performs registration between the first and scanned images. The second registration unit performs registration between the second image and the scanned image. The combining unit generates a master image by combining the first and second images based on registration results performed by the first and second registration units. The inspection unit inspects the printed matter by comparing the scanned image against the master image.

1. An image inspection apparatus comprising:
a first-image obtaining unit configured to obtain a first image generated by scanning a sheet on which a predetermined image has been printed in advance; a scanned-image obtaining unit configured to obtain a scanned image generated by scanning a printed matter produced by printing a second image additionally on the sheet; a second-image obtaining unit configured to obtain the second image; a first registration unit configured to perform registration between the first image and the scanned image; a second registration unit configured to perform registration between the second image and the scanned image; a combining unit configured to generate a master image by combining the first image and the second image based on a result of the registration performed by the first registration unit and a result of the registration performed by the second registration unit; and an inspection unit configured to inspect the printed matter by comparing the scanned image against the master image.
