Image Processing Control with Dynamic Medium Extension for Overlap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a read image of a document and an additional image overlap during output to a medium, the readability of both images is reduced, and the medium is often wasted due to being extended in an unpredictable manner.
Innovation Solution
An image processing apparatus that controls the output of a read image and an additional image to a medium, preventing overlap by increasing the medium's length in the sub-scanning direction when the significance portion of the read image and the specified region for the additional image overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medium length is extended to accommodate both the read image and additional image, then the images can be output without overlap, but the medium is wasted due to unpredictable extension
Solution Approach 1:
The system performs preliminary determination of whether the read image and additional image will overlap before outputting them to the medium. By checking the position information in advance and predicting potential overlap, the system can proactively adjust the medium length only when necessary, preventing both overlap and unnecessary medium waste.
Solution Approach 2:
The system dynamically changes the medium length parameter based on the actual overlap situation. Instead of extending the medium by a fixed or unpredictable amount, the system adjusts the extension length according to the specific position and size of the read image and additional image, optimizing medium usage while ensuring image readability.
2Area of stationary object
If the medium length is extended by a freely determined length, then the read image and additional image can be contained, but this results in waste of the medium
Solution Approach 1:
The system performs preliminary calculation of the required medium length by analyzing the position information of the read image and additional image before output. This allows the system to determine the minimum necessary extension length in advance, ensuring the medium is extended only by the exact amount needed to prevent overlap.
Solution Approach 2:
The system makes the medium length dynamic rather than fixed or freely determined. The extension length varies based on the actual overlap conditions, adjusting to different scenarios such as when the additional image is positioned at different locations relative to the read image, optimizing medium usage in each case.
3Quantity of substance
If the read image and additional image are output to the medium, then both images are preserved, but they overlap and reduce readability
Solution Approach 1:
The system performs preliminary determination of image overlap by checking position information before outputting both images to the medium. This advance check allows the system to identify potential overlap situations and take corrective action, ensuring both images are preserved while maintaining their readability.
Solution Approach 2:
The system introduces an intermediary control mechanism that manages the output process of both images. By controlling the output timing and position based on position information, this intermediary mechanism prevents direct overlap between the read image and additional image, preserving both images while ensuring their readability.

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 and an additional image are outputted to a medium with a significance portion and the additional image 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 a specified region of the read image to which the additional image is decided to be added overlap.
