Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing technologies face challenges in accurately setting and adjusting correction targets for skew correction, particularly in cases of distortion and uneven sheet sizes, leading to labor-intensive adjustments and potential image quality deterioration.
Innovation Solution
An image processing apparatus and method that allows for skew correction by deforming images in advance to offset distortions, with selectable execution options for skew correction based on sheet specifications, including one side, two sides, or external form, and prioritizing margin usage for high-priority corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If skew correction is executed by deforming image information, then image position adjustment with high degree of freedom is achieved, but correction target position cannot be appropriately set leading to labor-intensive adjustments
Solution Approach 1:
The system automatically detects sheet distortion and calculates correction parameters without user intervention. The image processing unit autonomously determines the correction target position and applies skew correction, eliminating the need for manual adjustment by operators.
Solution Approach 2:
The system uses detection results from the sheet distortion detection unit as feedback to automatically adjust image position. The correction amount is calculated based on detected distortion, creating a closed-loop system that eliminates manual trial-and-error adjustment.
2Manufacturing precision
If skew correction is executed by deforming image information, then image position adjustment with high degree of freedom is achieved, but margin is required in image print area reducing print productivity
Solution Approach 1:
The system performs skew correction by deforming image information before printing, compensating for anticipated sheet distortion. This preliminary action eliminates the need for post-print adjustment and reduces margin requirements, thereby improving print productivity.
3Manufacturing precision
If skew correction is executed, then image position adjustment is improved, but image quality may deteriorate
Solution Approach 1:
The system adjusts deformation parameters based on detected sheet distortion characteristics. By changing image deformation parameters dynamically according to actual sheet conditions, the system achieves precise position correction while minimizing image quality deterioration.
