Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately associate the front and back sides of sheets without pre-printed marks or text, leading to inefficiencies in processing and management.
Innovation Solution
An information processing apparatus and method that utilizes image data from both sides of sheets, employing positional relationships, attributes, and similarity calculations to associate front and back sides based on scanning or imaging, allowing for automatic pairing without pre-printed markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-printed marks or text are used for association, then association accuracy is improved, but device complexity and preparation work increase
Solution Approach 1:
The system automatically associates front and back sides of sheets by detecting positional relationships between sheets in stacked images, eliminating the need for pre-printed marks or manual intervention. The image processing apparatus self-determines associations based on spatial positioning data extracted from the images themselves.
Solution Approach 2:
The patent replaces physical marks or mechanical tagging systems with an optical/electronic solution using image capture and computational analysis. By substituting mechanical association methods with digital image processing, the system achieves automated association without physical modifications to the sheets.
2Productivity
If manual association methods are used, then device complexity is reduced, but productivity and processing efficiency decrease
Solution Approach 1:
The system creates digital copies (images) of the front and back sides of sheets and processes these copies to determine associations. By working with image data rather than physical sheets, the system enables automated processing while maintaining sheet integrity and improving throughput.
Solution Approach 2:
The patent replaces manual physical handling and association methods with automated image capture and computational algorithms. This substitution dramatically increases processing efficiency while the complexity is managed through software-based solutions rather than hardware complexity.
3Loss of time
If sheets are processed individually, then measurement precision can be maintained, but loss of time increases
Solution Approach 1:
The system merges multiple sheets into a single stacked arrangement for simultaneous imaging. By capturing front and back sides of multiple sheets in one operation, the system processes multiple items in parallel, reducing total processing time while maintaining association accuracy through unified positional analysis.
Solution Approach 2:
The image processing apparatus continuously captures images and processes associations without interruption. The system maintains steady-state operation by continuously acquiring image data and computing positional relationships, eliminating idle time between processing steps while preserving measurement precision through consistent processing methods.

AI summary
An information processing apparatus includes a processor configured to receive first image data representing front sides of plural sheets, that is generated by one reading, receive second image data representing back sides of the plural sheets, that is generated by one reading, and associate a front side and a back side of each sheet with each other, based on a positional relationship between each sheet represented in the first image data and each sheet represented in the second image data.
