Document Area Pattern Selection for Scanner Edge Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanner apparatuses with multi-crop functions face challenges in accurately extracting document areas, leading to errors in cutting multiple documents as one large document due to unclear document edges when black background paper is missed, and the complexity of user operations to correct erroneous document area extraction.
Innovation Solution
An information processing apparatus that displays multiple patterns of document areas extracted from an input image, allowing users to select the correct pattern, thereby simplifying the process of extracting accurate document areas and reducing user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If black background paper is used to increase contrast, then document edge clarity is improved, but operation complexity increases and errors may still occur
Solution Approach 1:
The system automatically extracts multiple document area patterns and presents them to the user for selection, eliminating the need for manual document repositioning or black background paper usage. The apparatus self-corrects by providing multiple extraction patterns including correct and erroneous ones, allowing users to simply select the correct pattern rather than performing complex manual operations.
2Productivity
If multiple documents are placed close together or aligned, then productivity is improved, but document area extraction accuracy deteriorates
Solution Approach 1:
The system segments the document area extraction into multiple distinct patterns, presenting each possible extraction result as a separate option to the user. This segmentation allows the system to handle closely placed or aligned documents by providing multiple extraction patterns, enabling users to select the correct document boundaries even when documents are positioned close together or overlap slightly.
3Ease of operation
If simple display of extracted document area is used, then ease of operation is improved, but accuracy of document area extraction deteriorates
Solution Approach 1:
The system provides feedback by displaying multiple extracted document area patterns to the user, allowing visual confirmation and selection of the correct extraction. This feedback mechanism maintains ease of operation while improving accuracy, as users can simply select from displayed patterns rather than performing complex manual corrections, ensuring only accurate document areas are processed further.

AI summary
An information processing apparatus includes a processor configured to, in a case where there are plural patterns of document areas extracted from an input image obtained by imaging documents, execute display control for displaying the plural patterns as options on a screen, receive selection of a correct pattern among the plural patterns according to the display of the screen through the display control, and extract an image of each document area included in the pattern selected by a user from the input image.
