Stamp Readability in Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stamp synthesis copying technologies often result in stamp character strings being overlapped with original document content, making them difficult to read, especially in multi-page documents.
Innovation Solution
An image processing apparatus that determines readability of stamp character strings by overlapping image data from a scanner with stored image data, generates a corrected image to improve readability by shifting or adjusting the stamp character string, and synthesizes this corrected image with the scanner image to ensure clear visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stamp characters are disposed at a fixed position for synthesis copying, then copying efficiency is improved, but readability of stamp character string deteriorates due to overlap with original document content
Solution Approach 1:
The patent applies dynamics by making the stamp character position variable rather than fixed. The determination unit dynamically adjusts the stamp character position based on the scanned original document content, selecting positions that avoid overlap with important document elements while maintaining efficient copying operation
Solution Approach 2:
The patent implements feedback by using the determination unit to evaluate the scanned original document and provide feedback on suitable stamp character positions. The system reads the original document, determines optimal positioning based on content analysis, and adjusts stamp character placement accordingly to ensure readability
2Speed
If stamp characters are overlapped with original document content, then copying speed is improved, but readability of stamp character string deteriorates
Solution Approach 1:
The patent applies preliminary action by performing determination of optimal stamp character positions before the actual copying process. The determination unit analyzes the scanned document and pre-determines suitable positions, so that when copying occurs, the stamp characters are already positioned to avoid overlap, maintaining both speed and readability
3Ease of operation
If stamp character position is fixed at copying start, then operation simplicity is improved, but readability varies across multiple pages
Solution Approach 1:
The patent applies universality by making the stamp character positioning system adaptable to different page contents. The determination unit universally evaluates each page's scanned content and automatically adjusts stamp character positions, making the system work effectively across all pages without requiring manual intervention for each page
Data Source
AI summary
An overlap determining unit determines whether or not a stamp character string is readable using image data of a stamp image and image data of a scan image read by a scanner unit when the stamp image and the scan image area overlapped. A stamp image generating unit generates a correction stamp image obtained by correcting the stamp image to improve readability of the stamp characters when it is determined that the stamp characters are not readable. A synthesis image generating unit generates a synthesis image in which the correction stamp image and the scan image are overlapped. A printer unit forms the synthesis image on a printing medium.
