IMAGE INSPECTION METHOD, IMAGE INSPECTION DEVICE, PROGRAM, AND IMAGE RECORDING SYSTEM
First Claim
1. An image inspection method comprising:
- an inspection image acquisition step of acquiring data of an inspection image obtained by capturing an image of a recorded matter recorded by an image recording system that comprises a plurality of image formation elements and performs a compensation process of compensating for a defect caused by a failure in the image formation element, using an imaging apparatus;
a reference image acquisition step of acquiring data of a reference image which is a reference for detecting a defect in the recorded matter; and
a defect detection step of comparing the data of the inspection image with the data of the reference image to determine whether there is a defect at each position of the inspection image,wherein the defect detection step includes a process that makes a defect detection performance different in a compensation application region and a compensation non-application region other than the compensation application region, on the basis of compensation position information of the failure in the image formation element to which the compensation process has been applied.

Abstract
The image inspection method includes: a step of acquiring data of an inspection image obtained by capturing an image of a recorded matter recorded by an image recording system that performs a compensation process of compensating for a defect caused by a failure in an image formation element, using an imaging apparatus; a step of acquiring data of a reference image; and a step of comparing the data of the inspection image with the data of the reference image to determine whether there is a defect at each position of the inspection image. The defect detection step includes a process that makes a defect detection performance different in a compensation application region and a compensation non-application region other than the compensation application region, on the basis of compensation position information of the failure in the image formation element to which the compensation process has been applied.

16. An image inspection device comprising:
-
an inspection image acquisition unit that acquires data of an inspection image obtained by capturing an image of a recorded matter recorded by an image recording system that comprises a plurality of image formation elements and performs a compensation process of compensating for a defect caused by a failure in the image formation element, using an imaging apparatus; a reference image acquisition unit that acquires data of a reference image which is a reference for detecting a defect in the recorded matter; and a defect detection unit that compares the data of the inspection image with the data of the reference image to determine whether there is a defect at each position of the inspection image, wherein the defect detection unit performs a process that makes defect detection performances different in a compensation application region and a compensation non-application region other than the compensation application region, on the basis of compensation position information of the failure in the image formation element to which the compensation process has been applied.

17. An image recording system comprising:
-
a plurality of image formation elements; a compensation processing unit that perform is a compensation process of compensating for a defect caused by a failure in the image formation element and reducing visibility of the defect; an imaging apparatus that captures an image of a recorded matter recorded by the image formation elements; an inspection image acquisition unit that acquires data of an inspection image obtained by capturing the image of the recorded matter using the imaging apparatus; a reference image acquisition unit that acquires data of a reference image which is a reference for detecting a defect in the recorded matter; and a defect detection unit that compares the data of the inspection image with the data of the reference image to determine whether there is a defect at each position of the inspection image, wherein the defect detection unit performs a process that makes a defect detection performance different in a compensation application region and a compensation non-application region other than the compensation application region, on the basis of compensation position information of the failure in the image formation element to which the compensation process has been applied.
