Thumbnail Keyword Overlay for Document Search Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing methods face low search efficiency due to low visibility of A4-sized documents and spreadsheet data when displayed in thumbnail form, making it difficult to recognize and search large amounts of image data.
Innovation Solution
An image processing method that overlaps keywords with thumbnail images, using a displaying unit, storage unit, and control unit to analyze and display keywords in a format that enhances visibility, such as using a semi-transparent layer, adjusting character size, color, and position based on keyword and image data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image data is displayed in thumbnail form to enable browsing of large amounts of data, then the quantity of data that can be viewed increases, but the visibility and recognizability of document content decreases
Solution Approach 1:
The patent segments the information display by separating the image thumbnail from the keyword information. Keywords are extracted and displayed as distinct text elements overlaid on or near the thumbnail, allowing the small thumbnail image to convey category information while keywords provide detailed content identification.
Solution Approach 2:
The patent adds a textual dimension to the visual thumbnail display by overlaying keywords. This transforms the display from purely visual (thumbnail) to a combination of visual and textual information, enabling content recognition in the limited thumbnail space.
2Difficulty of detecting and measuring
If keyword is overlaid on thumbnail image to improve content visibility, then the recognizability of document data increases, but the display complexity increases
Solution Approach 1:
The patent merges the thumbnail image display with keyword text display into a single integrated view. The keyword information is overlaid on or positioned near the thumbnail, combining visual and textual information in one display element without requiring separate display devices or complex multi-panel arrangements.
Solution Approach 2:
The patent uses keywords as an intermediary element that bridges the thumbnail image and the full document content. Keywords are extracted from the document and serve as a textual mediator that provides content information in the thumbnail view, enabling recognition without displaying the full document.
3Measurement precision
If multiple keywords are displayed on thumbnail to improve search accuracy, then the search precision increases, but the thumbnail becomes cluttered and harder to view
Solution Approach 1:
The patent extracts only the most relevant keywords from the document content and selects a limited number for display on the thumbnail. Rather than displaying all possible keywords, the system identifies and extracts key terms that best represent the document content, maintaining thumbnail clarity while providing sufficient search information.
Solution Approach 2:
The patent applies different display qualities to different parts of the thumbnail by positioning keywords in specific locations and using varying text sizes or styles based on their importance. Critical keywords receive more prominent display treatment while less important ones are displayed more subtly, optimizing both information delivery and visual clarity.
Data Source
AI summary
An image processing method executed by an image processor comprising a displaying unit, a storage unit, and a control unit, wherein the storage unit includes an image data storage unit that stores image data displayed in thumbnail form and a keyword associated with the image data, and the method includes a keyword obtaining step of obtaining the keyword corresponding to the image data stored in the image data storage unit; and a thumbnail image with keyword displaying step of displaying the keyword obtained at the keyword obtaining step on the displaying unit, with the keyword being overlapped with the image data.
