Image Reading Apparatus Previewing Pages With Low Determination Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image reading apparatuses, users face inefficiencies when previewing large documents for correcting erroneous image processing, as they must manually check each page, leading to distraction and increased risk of overlooking pages needing correction, especially when documents have similar images.
Innovation Solution
An image reading apparatus and method that allows users to preview only pages with a high possibility of erroneous determination by setting extraction conditions based on characteristics, using a scanner unit, image processing unit, display device, and controller to narrow down pages with determination accuracy below a predetermined standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually check each page of a large document on the preview screen, then they can verify the read document images, but it is time consuming and cumbersome leading to user distraction and increased risk of overlooking pages needing correction
Solution Approach 1:
The patent extracts and separates pages with low determination accuracy from the complete document set. The controller identifies pages where determination accuracy is below a predetermined standard and extracts only these pages for preview display, allowing users to focus correction efforts on problematic pages rather than manually reviewing every page of a large document
Solution Approach 2:
The patent creates a filtered copy of the document consisting only of pages with low determination accuracy. Instead of requiring users to examine the complete original document, the system generates and displays a simplified preview containing only the pages that need attention, significantly reducing the time required for quality verification
2Reliability
If users check all pages of a large document, then they can ensure quality, but user attention is distracted and the risk of overlooking pages that need correction increases
Solution Approach 1:
The system extracts and isolates only the pages with low determination accuracy for preview display. This extraction process maintains reliability by ensuring that all pages needing correction are identified through automated determination, while simultaneously improving ease of operation by presenting a condensed, focused view that eliminates unnecessary pages from the user's review process
Solution Approach 2:
The system performs self-service by automatically identifying and filtering pages that require user attention. The controller autonomously determines which pages have low accuracy and prepares the preview accordingly, reducing the cognitive load on users and eliminating the need for them to manually assess every page while maintaining high correction accuracy

AI summary
An image reading apparatus includes: a scanner unit that scans a document including a plurality of pages and reads an image of each of the pages; an image processing unit that determines characteristics of each page of the read images and performs image processing in accordance with the characteristics; a display device that previews the processed image of each page; an operation detection device that accepts a setting of an extraction condition related to the characteristics; and a controller that extracts, based on the set extraction condition, and previews a read image of a page having determination accuracy pertaining to the characteristics below a predetermined standard among the images processed for each page.
