  • Publication number: 20120162706
    Abstract: A main body controller provided in an image forming apparatus receives a VDP job from an external computer, and arranges image data of a reusable object and a variable object, which correspond to the VDP job, on a page for printout. An inspection controller performs inspection processing for printed matter for each page, and the main body controller preferentially stores image data of the reusable object, which corresponds to the page for which the printing has been determined to be defective as a result of inspection processing, in a cache unit. The main body controller acquires the reusable object, which corresponds to the page for which the printing has been determined to be defective, from the cache unit, and executes page reprint processing using the acquired reusable object.

  • Patent number: 8155395
    Abstract: An iris authentication apparatus includes an iris area extraction unit, registration pattern generating unit, collation pattern generating unit, and collation unit. The iris area extraction unit extracts iris areas from a sensed registration eyeball image and a sensed collation eyeball image. When the iris area extraction unit extracts an iris area from the registration eyeball image, the registration pattern generating unit generates a registration iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. When the iris area extraction unit extracts an iris area from the collation eyeball image, the collation pattern generating unit generates a collation iris pattern image by performing polar coordinate transformation of an image in the extracted iris area.

  • Publication number: 20110135321
    Abstract: If a print misregistration amount on a sheet is larger than a predetermined threshold before determining whether a printed image is appropriate or not, an abnormal status of the image printed on the sheet is detected without correcting image data for inspection. A control method for controlling a detecting apparatus for inspecting a print status of an image printed on a sheet by a printing apparatus includes detecting, in a case where it is determined that a print misregistration amount of the image printed on the sheet with respect to the sheet is larger than a predetermined threshold, an abnormality of the print status of the image read by a reading unit without performing correction.
