Document Reading Guidance for Large Format Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reading technologies face challenges in efficiently processing documents larger than the readable size of a scanning apparatus, requiring multiple scans and often resulting in image synthesis with reduced quality due to inadequate alignment of feature areas.
Innovation Solution
A reading method guidance apparatus that includes a receiving unit, an acquisition unit, and a guidance unit, which receives document size and acquires images of partial areas to generate a reading procedure using feature amounts, ensuring optimal alignment and overlap of areas with significant feature changes for accurate synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a document larger than readable size is read in multiple batches, then the document can be fully captured, but the image synthesis quality deteriorates due to inadequate alignment of feature areas
Solution Approach 1:
The system performs preliminary analysis of the document image to detect feature areas with large feature amounts before the actual reading process. Based on this preliminary detection, it pre-determines the optimal reading procedure including batch division, overlap regions, and reading positions. This preliminary action ensures that feature areas are properly captured in overlapping regions, thereby maintaining high image synthesis quality while reading documents larger than the readable area.
2Area of stationary object
If multiple batches are used to read large documents, then the entire document can be captured, but the reading procedure becomes complex and time-consuming
Solution Approach 1:
The system performs preliminary detection of feature areas and pre-calculates the optimal reading procedure including the number of batches, overlap regions, and reading positions. This preliminary analysis creates a optimized reading plan that minimizes the number of batches required while ensuring complete document capture. By determining the reading procedure in advance based on feature area distribution, the system avoids unnecessary batches and reduces overall reading time.
3Ease of operation
If feature areas are not properly aligned in overlapping regions, then the reading process is simpler, but the synthesized image quality deteriorates
Solution Approach 1:
The system automatically detects feature areas with large feature amounts in the document image and self-determines the optimal reading procedure without requiring manual intervention. It automatically calculates which regions should be overlapping areas and ensures feature areas are properly positioned in these overlaps. This self-service approach maintains reading procedure simplicity while achieving precise feature area alignment through automated analysis and planning.

AI summary
A reading method guidance apparatus includes a receiving unit, an acquisition unit, and a guidance unit. The receiving unit receives a document size that is a size of a document as a reading target. The acquisition unit acquires an image of at least a partial area in the document. The guidance unit provides an operator with guidance about a reading procedure when the document is read by a first reading apparatus in plural batches, using a feature amount obtained from the acquired image, the received document size, and a readable size that is a size of an area readable by the first reading apparatus.
