Image Processing Apparatus Combines Small-Sheet Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems struggle to accurately extract small-sheet images, such as name cards, from scanned images, often resulting in multiple small-sheet images being incorrectly extracted and difficult to associate with the original, leading to errors and laborious correction processes.
Innovation Solution
An image processing apparatus is developed with a generation unit that combines multiple small-sheet images into a single image when they are unsuccessfully extracted, using modules like image acquisition, separation, determination, and generation to assess and correct extraction errors by setting circumscribed rectangles and determining skew, thereby facilitating easier identification and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple small-sheet images are extracted separately, then extraction precision is improved, but ease of operation deteriorates because users cannot easily associate extracted images with original sheets
Solution Approach 1:
The patent combines multiple extracted small-sheet images that belong to the same original sheet into a single composite image. This allows users to view all extracted portions together, making it easy to identify which original sheet has extraction errors while maintaining the precision of individual image extraction through the combination process.
2Measurement precision
If multiple small-sheet images are extracted separately, then extraction precision is improved, but productivity deteriorates due to laborious correction processes
Solution Approach 1:
By merging multiple extracted images into a single composite image, the patent reduces the number of images users need to check individually. This significantly improves correction efficiency while maintaining extraction precision, as users can identify errors in one composite image rather than searching through multiple separate images.
3Ease of operation
If combined images are generated for unsuccessfully extracted sheets, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent segments the image processing into distinct stages: initial extraction of small-sheet images, determination of which sheets were unsuccessfully extracted, and combination of those extracted images into composite images. This segmentation manages processing complexity by organizing operations into manageable steps while improving ease of operation.
Solution Approach 2:
The system performs preliminary determination of which small sheets were unsuccessfully extracted before combining their images. This preliminary action allows the system to prepare composite images only for sheets that need correction, managing processing complexity efficiently while improving ease of operation for error identification.
