Abstract
The present invention provides an inspection apparatus that inspects an image formed on a recording medium by a printing apparatus. The inspection apparatus stores, as a reference image, image data used to form an image on the recording medium, obtains target image data to be inspected, by reading an image to be inspected formed on the recording medium. The inspection apparatus applies noise components to the reference image, aligns the reference image to which the noise components have been applied with the target image data, and performs collation processing between the reference image and the target image data that have been aligned.
Claims15
An inspection apparatus that inspects an image formed on a recording medium by a printing apparatus, the inspection apparatus comprising:
- one or more controllers including one or more processors and one or more memories, the one or more controllers being configured to:
- store, as a reference image, image data used to form an image on the recording medium;
- obtain target image data to be inspected, by reading an image to be inspected formed on the recording medium;
- apply random numbers to respective pixels of the reference image;
- align the reference image to which the random numbers have been applied with the target image data;
- and
- perform collation processing between the reference image and the target image data that have been aligned.
A method of controlling an inspection apparatus that inspects an image formed on a recording medium by a printing apparatus, the method comprising:
- storing, as a reference image, image data used to form an image on the recording medium;
- obtaining image data to be inspected, by optically reading the image formed on the recording medium;
- applying random numbers to respective pixels of the reference image;
- aligning the reference image to which the random numbers have been applied with the target image data;
- and
- performing collation processing between the reference image and the target image data that have been aligned.
A non-transitory computer-readable storage medium storing a program for causing a processor to execute a method of controlling an inspection apparatus that inspects an image formed on a recording medium by a printing apparatus, the method comprising:
- storing, as a reference image, image data used to form an image on the recording medium;
- obtaining image data to be inspected, by optically reading the image formed on the recording medium;
- applying random numbers to respective pixels of the reference image;
- aligning the reference image to which the random numbers have been applied with the target image data;
- and
- performing collation processing between the reference image and the target image data that have been aligned.
