US 11,627,226 B2 · Image processing apparatus, control method, and product for determining defect reproducibility based on defect positions on recording media calculated from phase information

Abstract

This disclosure provides an image processing apparatus that is connected to a printing apparatus, sequentially receives a plurality of recording media on which printing was performed by the printing apparatus, and inspects a quality of images formed on the recording media, wherein the image processing apparatus receives a reference image, acquires a plurality of scanned images by sequentially scanning the recording media output from the printing apparatus and having the images to be inspected recorded thereon, receives phase information of an image bearing member of the printing apparatus, detects, for each of the scanned images, a defect on the scanned image by comparing a pixel value of the reference image and a pixel value of the scanned image, and determines whether a defect has reproducibility based on positions of defects on the recording media calculated from the phase information.

An image processing apparatus that is to be connected to a printing apparatus, that sequentially receives a plurality of recording media on which printing was performed by the printing apparatus, and that inspects a quality of images formed on the recording media, the image processing apparatus comprising:

a processor;
and
a memory storing instructions to be executed by the processor, wherein the instructions, when executed by the processor, cause the image processing apparatus to function as:
a reference image reception unit configured to receive a reference image;
a scanned image reception unit configured to acquire a plurality of scanned images by sequentially scanning the recording media output from the printing apparatus and having the images to be inspected recorded thereon;
a phase information reception unit configured to receive phase information of an image bearing member of the printing apparatus;
a defect detection unit configured to, for each of the scanned images, detect a defect on the scanned image by comparing a pixel value of the reference image and a pixel value of the scanned image;
and
a determination unit configured to determine whether a defect has reproducibility based on positions of defects on the recording media calculated from the phase information.
