N-Up Document Content Scaling for Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face usability issues and increased computation requirements when viewing electronic documents on computing devices due to limited display resolution, requiring frequent zooming and panning, and N-Up documents often have font sizes that are difficult to read without access to the original page images.
Innovation Solution
A method and system that extract and analyze page images from N-Up documents, determine content size, and modify it based on a pre-determined threshold value received from the user, using processors to optimize font sizes for improved readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If multiple page images are printed/copied/scanned in a single N-Up document to save paper, then paper usage is reduced, but font size becomes too small to read
Solution Approach 1:
The system segments the N-Up document into individual page images, analyzes content distribution in each segment, and applies selective scaling to pages with insufficient font sizes while maintaining the N-Up layout for pages with adequate font sizes
Solution Approach 2:
The patent applies different quality treatments to different parts of the document - pages with sufficient font sizes are kept in the original N-Up format to save space, while pages with insufficient font sizes are extracted, scaled up, and processed individually to ensure readability
2Ease of operation
If users manually zoom-in/out to improve readability of content, then font size becomes readable, but user interaction time and computation requirements increase
Solution Approach 1:
The system automatically detects pages with insufficient font sizes, extracts them, scales them to appropriate sizes, and processes them without requiring user intervention - the document processing system serves itself by identifying and correcting readability issues autonomously
Solution Approach 2:
The patent performs preliminary analysis of content distribution and font sizes in the N-Up document before final processing, identifying pages that require scaling in advance so that when the document is rendered, all pages are already optimized for readability without requiring user zooming
3Quantity of substance
If original page images are not available for N-Up documents with difficult-to-read font sizes, then document storage is optimized, but it becomes difficult to obtain documents with desired font size
Solution Approach 1:
The system extracts individual page images from the N-Up document that have insufficient font sizes, processes them separately with scaling operations, and integrates them back - this extraction enables font size adjustment without needing the original separate page images

AI summary
Various embodiments for methods and systems for processing documents are disclosed. A size of at least a part of a content in an electronic document is determined. Size of the part of the content is modified based at least on a pre-determined threshold value for size and the determined size. Further, various embodiments for methods and systems for processing N-Up documents are disclosed. One or more page images from an N-Up document are extracted based on an analysis of a content distribution in the N-Up document. A size of a content in at least a part of extracted one or more page images is determined. The size of the content is modified in accordance to a pre-determined threshold value receive from a user.
