Document Type and Number:
Japanese Patent JP2022162422
Kind Code:
A
Abstract:
To provide an image processing system, an image processing method, and a program that detect a defect occurring in a read image obtained by reading a plurality of patches.SOLUTION: In an image processing system, an alignment unit 206 of a patch position analysis unit 204 executes alignment processing of each patch area from a read image of a test chart and a master image. A defect detection unit 208 uses a similarity change amount calculation unit 209 to detect an outlier in a similarity distribution of a plurality of patches in the aligned read image and the master image, and uses a position deviation amount calculation unit 210 to detect the outlier in a distribution of the positions of the plurality of patches in the read image. A UI generation unit 212 displays, when an outlier is detected in at least one of similarity of the plurality of patches and the position of the plurality of patches, and an error patch is detected, a message indicating a similarity error or a patch position error and a position of the error patch.SELECTED DRAWING: Figure 2
