Image Processing Apparatus Selective Document Inclination Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing systems, when documents are inclined beyond a certain threshold, the inclination correction process can result in shifting during document cover opening or closing, leading to incomplete or inaccurate correction, causing unexpected results for users.
Innovation Solution
An image processing apparatus with an input unit for reading document images, a determination unit to assess inclination correction acceptance, a selection unit to identify documents not accepting correction, and an output unit to handle these documents separately, ensuring appropriate processing and user confirmation before printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inclination correction process is performed on all documents, then processing completeness is improved, but documents that cannot be corrected produce unexpected results and waste user time
Solution Approach 1:
The patent applies partial action by selectively performing inclination correction only on documents that can be properly corrected, while excluding documents that exceed correction thresholds. The control unit identifies problematic documents and excludes them from the correction process, preventing waste of user time on uncorrectable documents while still processing all correctable documents completely.
Solution Approach 2:
The patent uses feedback by having the control unit monitor the inclination correction process, detect when documents cannot be properly corrected, and automatically adjust the processing to exclude those documents. This feedback mechanism prevents the system from continuing to process uncorrectable documents, thereby avoiding user time waste while maintaining processing completeness for valid documents.
2Ease of operation
If documents are reset after cover opening/closing, then documents can be repositioned, but previously corrected documents may become further inclined and lose correction acceptance
Solution Approach 1:
The patent applies preliminary action by having the control unit identify and exclude documents that cannot be corrected before the document cover is opened or closed. By determining correction feasibility in advance and excluding problematic documents beforehand, the system prevents the scenario where corrected documents become further inclined after reset, thus maintaining correction acceptance stability while still allowing easy document repositioning.
3Productivity
If inclination correction is performed on excessively inclined documents, then all documents are processed, but correction accuracy deteriorates and unexpected results occur
Solution Approach 1:
The patent applies partial action by performing inclination correction only on documents within acceptable correction thresholds. The control unit identifies documents that are excessively inclined and excludes them from correction processing, thereby preventing deterioration of correction accuracy while still maintaining high productivity by processing all correctable documents without interruption.
Data Source
AI summary
Image data corresponding to a plurality of documents placed on a document plate is individually output. In this case, if an inclined document is included in the documents, the document is output after being subjected to inclination correction. However, if a document which does not accept the inclination correction is included, documents other than the document are output.
