Abstract

In a case where an inspection level to be used in determining quality of an image of an inspected surface of a printed sheet is set based on a comparison between a captured image resulting from imaging the inspected surface and a reference image, a plurality of inspection regions varying in inspection level is set for the reference image. In a case where an overlap region is present in the plurality of inspection regions, an inspection level of the overlap region is identified based on a predetermined priority. Further, the identified inspection level of the overlap region is displayed.

First claim

What is claimed is:

1. An information processing apparatus that sets an inspection level to be used in determining quality of an image of an inspected surface of a printed sheet, based on a comparison between a captured image resulting from imaging the inspected surface and a reference image, the information processing apparatus comprising:
a memory containing instructions; and
a processor configured to execute the instructions to perform operations comprising:
setting a plurality of inspection regions varying in inspection level, for the reference image,
identifying, in a case where an overlap region is present in the plurality of inspection regions, the inspection level of the overlap region based on a predetermined priority, and
displaying the identified inspection level of the overlap region,
wherein the priority becomes higher as an inspection level becomes higher.

2. The information processing apparatus according to claim 1 , wherein the operations further comprise:
acquiring a captured image resulting from imaging an inspected surface of a printed sheet; and
determining quality of the inspected surface of the printed sheet, based on the acquired captured image, the reference image, and the set inspection level, wherein determining the quality comprises determining the quality using the identified inspection level of the overlap region in a case where the overlap region is present in the plurality of inspection regions.

3. The information processing apparatus according to claim 1 , wherein the operations further comprise receiving a display switching instruction,
wherein displaying comprises switching display from a screen displaying the identified inspection level of the overlap region to a screen displaying a frame of each of the plurality of inspection regions, in a case where receiving receives the display switching instruction.

4. The information processing apparatus according to claim 1 , wherein setting comprises setting an inspection exclusion region, and wherein the inspection exclusion region is assigned highest priority.

5. A method for controlling an information processing apparatus that sets an inspection level to be used in determining quality of an image of an inspected surface of a printed sheet, based on a comparison between a captured image resulting from imaging the inspected surface and a reference image, the control method comprising:
setting a plurality of inspection regions varying in inspection level, for the reference image;
identifying, in a case where an overlap region is present in the plurality of inspection regions, the inspection level of the overlap region based on a predetermined priority; and
controlling display to display the identified inspection level of the overlap region,
wherein the priority becomes higher as an inspection level becomes higher.

6. The method according to claim 5 , further comprising:
acquiring a captured image resulting from imaging an inspected surface of a printed sheet; and
determining quality of the inspected surface of the printed sheet, based on the acquired captured image, the reference image, and the set inspection level,
wherein the quality is determined using the identified inspection level of the overlap region in a case where the overlap region is present in the plurality of inspection regions.

7. The method according to claim 5 , further comprising receiving a display switching instruction,
wherein the display is switched from a screen displaying the identified inspection level of the overlap region to a screen displaying a frame of each of the plurality of inspection regions, in a case where the display switching instruction is received.

8. The method according to claim 5 , wherein in a case where an inspection exclusion region is set, the inspection exclusion region is assigned highest priority.
