Abstract
An inspection apparatus according to exemplary embodiments of the present disclosure includes a reception unit configured to receive print data, a registration unit configured to register an image included in the print data as a reference image, an extraction unit configured to extract information relating to a barcode inspection from the received print data, and an inspection unit configured to inspect, when a scanned image generated by scanning a print product is received, a barcode in the scanned image, based on the extracted information relating to the barcode inspection.
Claims8
An inspection apparatus comprising:
- one or more processors;
- and
- at least one memory storing executable instructions, which when executed by the one or more processors, cause the inspection apparatus to:
- perform reception to obtain received print data that include raster-image-processor (RIP) data of a print job;
- register an image included in the received print data as a reference image, delete the reference image after completion of an associated inspection job unless a re-inspection request is received, and thereby store at most one reference page per job in memory;
- extract, from the received print data, barcode-inspection information including a correct value represented by a barcode, an allowable quality level, and an image-area flag in which a bit value appended to each pixel indicates whether the pixel belongs to the barcode and output a barcode-position indicator derived from the bit values of the image-area flag;
- automatically incorporate the extracted barcode-inspection information into an inspection-parameter set without user interaction;
- and
- upon reception of a scanned image obtained by scanning a print product, determine a position of the barcode in the scanned image on the basis of the barcode-position indicator, and inspect the barcode by comparing a value obtained by decoding the barcode with the correct value and a decode accuracy with the allowable quality level, and, when the inspection is negative, output a defect-ejection signal to a purge accessory of a printing apparatus.
