Document Image Preview Omitting Intermediate Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During document scanning, large-format documents often experience shifts or meandering, leading to increased operational burden for users when the entire scanned image is displayed, as they need to manage image enlargement and movement, reducing visibility and increasing user effort.
Innovation Solution
An image processing system that displays only the right and left end portions of the document image on the screen, omitting the intermediate portion, allowing for enlarged preview of the end portions and adding additional images like guidelines to aid in skew determination and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entire scanned image is displayed during scanning, then the user can see the full document, but the image must be reduced in size for large documents, making it difficult to see details and increasing operational burden
Solution Approach 1:
The patent divides the document image into multiple segments: a first image showing the entire document at reduced scale, and a second image showing an enlarged view of a specific region of interest. This segmentation allows users to see both the overall document layout and detailed portions simultaneously without having to manually zoom or pan, thereby reducing operational burden while maintaining ease of viewing both overview and details
Solution Approach 2:
The patent adds a temporal dimension to the display by showing multiple images (overview and detailed view) concurrently or sequentially on the display unit. This dimensional approach allows users to access different levels of magnification without manual intervention, transforming the single-view limitation into a multi-view solution that reduces operational complexity
2Loss of information
If the entire scanned image is displayed during scanning, then the user can monitor the full document, but image enlargement or movement operations are required for detailed viewing, increasing operational burden
Solution Approach 1:
The system performs preliminary identification of regions of interest or important document portions before displaying the final multi-view image. By pre-processing the image to determine which areas require enlargement, the system eliminates the need for users to manually zoom or pan, thereby preserving document detail visibility while reducing operational burden
Solution Approach 2:
The system automatically performs image enlargement and region selection without requiring user operations. The display unit autonomously presents both the overview image and the enlarged detailed image based on automated analysis, making the system self-serving and eliminating manual intervention for detail viewing

AI summary
In an image processing system, in an operation mode in which a document image scanned from a document being transported by a transport mechanism is displayed as a preview on a display unit, the preview of the document image by the transport mechanism is displayed in a form in which an intermediate portion located between end portions of the document in a direction intersecting a direction of transport by the transport mechanism is omitted.
