Inspection Display Layout for Locating Print Image Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display units for large-sized printed matter often only show a part of the inspection result image in an enlarged manner, making it difficult to distinguish the relationship between the inspection result image and the abnormal image, and unclear the position of the abnormal image.
Innovation Solution
An inspection apparatus with a reader, inspector, and display device that includes a first display region for the entire read image and a second display region for enlarged partial images, controlled to display abnormal images differently based on their presence in the first region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the inspection result image is displayed in an enlarged manner to show details of abnormal images, then the visibility of abnormal images is improved, but the display unit can only show a part of the inspection result image, making the position of abnormal images unclear
Solution Approach 1:
The display screen is divided into multiple display regions: a first display region showing the entire inspection result image to provide position context, and a second display region showing enlarged portions of the inspection result image to provide detail visibility. This segmentation allows both full-context positioning and detailed inspection to coexist simultaneously.
2Loss of information
If the entire inspection result image is displayed to show the position of abnormal images, then the position information is preserved, but the abnormal images cannot be viewed in detail
Solution Approach 1:
The solution transitions from a single-dimensional display (either entire image or enlarged portion) to a two-dimensional display layout with multiple regions serving different functions. The first display region maintains the overall position context while the second display region provides magnified detail view, effectively adding a spatial dimension to the information presentation.
3Illumination intensity
If only a part of the inspection result image is displayed in an enlarged manner to focus on abnormal areas, then the detail visibility is improved, but the relationship between the displayed portion and the entire image becomes unclear
Solution Approach 1:
The first display region acts as an intermediary that maintains the contextual relationship between the enlarged abnormal image portion and the entire inspection result image. By displaying the full image in the first region simultaneously with the enlarged portion in the second region, the system provides a reference framework that helps users understand the location and context of the detailed view.

AI summary
An inspection apparatus includes a reader configured to read a sheet on which an image has been formed, an inspector configured to inspect a read image that has been read by the reader, a display device configured to display a display screen including a first display region in which an entirety of the read image is displayable and a second display region in which a part of the read image is displayed in an enlarged manner, and a controller configured to control the display device, wherein the controller is configured to, display, in a case where there is a first abnormal image in the read image inspected by the inspector, the read image in the first display region.
