Multi-Function Device Scanning with Content-Aware Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies when scanning documents with multiple pages, as they must manually segregate and scan pages at different resolutions, leading to increased time and potential size limitations for email sharing.
Innovation Solution
A method and system for a multi-function device that allows users to input keywords and desired resolution values, automatically generating multiple scanned files of different resolutions from a single scan, eliminating the need for manual segregation and separate scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all pages are scanned at higher resolution (600 DPI), then the quality of images and charts is improved, but the file size increases beyond email limits
Solution Approach 1:
The patent applies local quality by scanning different pages of the document at different resolutions based on their content requirements. Pages containing images or charts are scanned at higher resolution (600 DPI) to maintain quality, while pages with only text are scanned at lower resolution (200 DPI) to reduce file size. This selective approach ensures that high-quality scanning is applied only where necessary, resolving the contradiction between overall quality and file size constraints.
2Quantity of substance
If all pages are scanned at lower resolution (200 DPI), then the file size is reduced, but the resolution and quality of charts and images deteriorates
Solution Approach 1:
The system analyzes each page's content characteristics and applies appropriate resolution locally. Pages with text-only content receive lower resolution (200 DPI) scanning to minimize file size, while pages detected to contain images or charts receive higher resolution (600 DPI) scanning to preserve quality. This content-based selective scanning resolves the contradiction by matching resolution quality to actual content requirements.
3Manufacturing precision
If user manually segregates document into different parts for different resolutions, then different resolution scanning can be achieved, but the process becomes time-consuming and complex
Solution Approach 1:
The patent implements self-service by enabling the scanning system to automatically analyze document content and determine appropriate resolution requirements for each page without user intervention. The system autonomously identifies pages containing images or charts versus text-only pages and applies corresponding resolution settings, eliminating the need for users to manually segregate documents and significantly reducing processing time while maintaining differential resolution scanning capabilities.
4Manufacturing precision
If user scans document parts separately at different resolutions, then quality control is achieved, but the operation becomes complicated requiring third-party software
Solution Approach 1:
The patent merges multiple scanning operations into a single unified process. Instead of requiring users to separately scan different document portions at different resolutions and then collate them using third-party software, the system combines content analysis, resolution determination, and multi-resolution scanning into one integrated operation. The user simply loads the entire document, and the system handles all resolution decisions and processing in a single workflow, maintaining quality control while dramatically simplifying the user experience.
Data Source
AI summary
The disclosure discloses methods and systems for automatically generating multiple scanned files when scanning a document at a multi-function device. The method includes receiving a multi-page document for scanning from a user. A user interface is provided to the user to input one or more keywords and one or more desired resolution values, where the input resolution values are different from a default resolution value set at the multi-function device. A page of the document is scanned to generate a scanned page of a default resolution value. The scanned page is checked if including the one or more input keywords. Accordingly, the default resolution value of the page is converted to the user desired resolution value. The scanning, checking, and converting are repeated till all the pages of the document are scanned. Multiple scanned files of different resolution values are automatically generated from single scan activity.
