Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems require significant hardware resources, such as high CPU processing capacity and memory, to manage and analyze printed materials, leading to processing latency and memory exhaustion in systems with lower resource capabilities.
Innovation Solution
An image processing apparatus that acquires region information from printed materials by analyzing print data, superimposes objects indicating filled regions on read images, and allows user input for confirmation, enabling efficient analysis and scoring without the need for extensive hardware resources.

Engineering Contradiction Analysis
1Productivity
If conventional image recognition or AI processing is used to manage printed material information, then the system can perform electronic scoring and content analysis, but sufficient hardware resources (CPU, memory) are required, causing processing latency and memory exhaustion in image processing apparatuses with lower resource capabilities
Solution Approach 1:
The patent segments the image processing task into multiple stages: first extracting print data and generating a management file with region information, then using this pre-processed data for subsequent analysis. This segmentation allows the system to perform complex operations in steps, reducing the memory burden on any single processing stage and enabling apparatuses with limited resources to handle the tasks sequentially rather than requiring all resources simultaneously.
2Reliability
If a management computer with high processing capability is provided separately from the printing apparatus, then the system can perform content analysis and electronic scoring, but the device complexity and system configuration become more complex
Solution Approach 1:
The patent creates a management file that contains region information applicable to multiple different printed materials and analysis tasks. This management file serves as a universal data structure that can be used across various printing apparatuses and for different types of content analysis (scoring, extraction, recognition), eliminating the need for separate specialized systems while maintaining analysis performance.
3Ease of operation
If image recognition processing is performed on the printing apparatus itself, then the system can provide integrated functionality, but processing latency increases due to insufficient CPU capacity
Solution Approach 1:
The patent performs preliminary processing by extracting print data and generating management files with region information during the printing stage. This pre-extraction of structural information (frames, answer fields, score regions) allows subsequent recognition and scoring operations to work with already-processed data, significantly reducing the time required for actual content analysis while maintaining integrated functionality.

AI summary
An image processing apparatus acquires region information on one or more regions on a printed material which are to be filled in is acquired, the region information being obtained by analyzing print data of the printed material. An image processing apparatus superimposes an object indicating a region corresponding to the region information on a read image obtained by reading a printed material on which one or more regions have already been filled in, and displays the result on a display unit. Further, the image processing apparatus sets a confirmation result for each of the one or more regions in accordance with user input that was inputted via the display unit.
