IMAGE PROCESSING DEVICE AND METHOD OF DETECTING MISSING DOTS IN AN IMAGE PROCESSING DEVICE

摘要

An image processing device for detecting a large number of missing dots. The image processing device comprises a print data image acquisition unit that acquires a print data image; an inkjet printer unit that prints on the back of a check; a back CIS unit that scans the back of the printed check; a print area extraction unit that extracts a print area R from the scanned image of the back of the check as an extracted image; and a missing dot detection unit determines if there are missing dots based on the print data image and the extracted image extracted by the print area extraction unit.

主权项

1. An image processing device comprising:
a print data image acquisition unit that acquires a print data image based on print data; a print unit that executes a printing process based on the print data on a recording medium by ejecting ink from an inkjet head with a nozzle row of plural nozzles in a line and forming dots; a scanning unit that captures a scanned image of the recording medium after printing thereon by the print unit; a print area extraction unit that extracts a printed area of the scanned image of the recording medium captured by the scanning unit as an extracted image; and a missing dot detection unit that detects if there are missing dots based on the print data image and the extracted image of the printed area extracted by the print area extraction unit.
