Document Read Image Output with Adaptive Edge Margins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems waste media by outputting documents to larger media sizes when significance portions overlap edge regions, leading to unnecessary paper usage.
Innovation Solution
An image processing apparatus that controls the output of read images to prevent significance portions and edge regions from overlapping by adding margin images and adjusting the medium length in the sub-scanning direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a medium with size larger than the read image and closest to the read image is selected, then the medium size is optimized, but the significance portion may overlap with the edge region causing content loss
Solution Approach 1:
The system performs preliminary analysis of the read image to detect the significance portion before output processing. By提前 identifying important content regions, the system can pre-calculate appropriate margin distances and adjust medium selection to prevent overlap between significance portions and edge regions, thus avoiding content loss while optimizing medium usage
Solution Approach 2:
The system introduces margin images as an intermediary element between the significance portion and the medium edge. These margin images create a buffer zone that prevents direct overlap, allowing the significance portion to be preserved completely while still utilizing the medium efficiently. The margin acts as a mediator that resolves the conflict between content preservation and medium optimization
2Reliability
If the read image is outputted to a medium with larger size, then the entire read image including edge region is captured, but media waste occurs when significance portion does not require the full medium
Solution Approach 1:
The system applies different quality requirements to different regions of the read image. The significance portion requires high fidelity and complete preservation, while the edge region can be reduced or eliminated if it contains no important information. This local differentiation allows the system to preserve necessary content while reducing medium usage by excluding unnecessary edge regions
Solution Approach 2:
The system dynamically changes the output parameters based on the analyzed significance portion. By adjusting the effective output area, margin distances, and medium selection criteria according to the actual content requirements, the system optimizes medium usage while ensuring all significant content is preserved. This parameter adaptation prevents both over-use and under-use of medium
3Loss of substance
If the edge region is erased to prevent overlap, then media waste is reduced, but the significance portion may be compromised if it extends to the edge
Solution Approach 1:
The system implements a feedback mechanism that continuously monitors the relationship between the significance portion and the medium edge during output processing. If the significance portion is detected to extend toward the edge region, the system automatically adjusts margin distances or expands the output area to maintain content integrity. This real-time feedback ensures that media waste is minimized only when it does not compromise significance portion preservation

AI summary
An image processing apparatus includes a processor configured to: acquire a read image of a document that is read by a document reading apparatus; and control an image output device such that the read image is outputted to a medium with a significance portion and an edge region prevented from overlapping, and a length of the medium in a sub scanning direction is increased in a case where the significance portion of the read image and the edge region in the sub scanning direction in which the read image is outputted to the medium overlap.
