Thumbnail-Based Image Sharing via Feature Factor Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image sharing technologies are limited to single applications, preventing cross-application sharing of high-definition images using thumbnails, where only thumbnails or original images can be shared, but not both across different applications.
Innovation Solution
Creating feature factor indexes for all images in memory and buffers across applications and using these indexes to find and retrieve original high-resolution images based on thumbnail features, enabling cross-application image sharing by matching thumbnail features with a feature factor index library.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image sharing is limited to single application to ensure data security and simplicity, then device complexity and security management are reduced, but adaptability and cross-application sharing capability deteriorate
Solution Approach 1:
The patent introduces a system-level image sharing mechanism that acts as an intermediary between different applications. The system extracts feature factors from images and creates feature factor indexes at the system level, enabling cross-application image retrieval without requiring complex inter-application communication protocols. This intermediary layer simplifies the overall architecture while enabling versatile cross-application sharing.
Solution Approach 2:
The patent creates a universal image sharing mechanism that can be accessed by multiple applications through a common interface. The feature factor index library serves as a universal resource that any application can query, allowing a single image to be shared across multiple applications without requiring separate sharing implementations for each application pair.
2Loss of energy
If only thumbnails are shared to reduce transmission bandwidth, then bandwidth consumption is reduced, but image quality and information completeness deteriorate
Solution Approach 1:
The patent performs preliminary extraction of feature factors from images and creates feature factor indexes in advance, before any sharing operation occurs. This preliminary action enables rapid image retrieval and sharing of original high-definition images without requiring real-time image processing or full image transmission for matching, thus reducing bandwidth consumption while preserving image quality.
Solution Approach 2:
The patent creates feature factor copies or representations that serve as indexes for original images. Instead of transmitting or processing full-resolution images for every comparison operation, the system uses these compact feature factor copies to identify and retrieve original images, significantly reducing transmission bandwidth while maintaining the ability to access complete image information when needed.
3Productivity
If feature factor indexes are created for all images across applications to enable cross-application sharing, then adaptability and sharing capability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent implements automatic feature factor extraction and index creation mechanisms that operate without manual intervention. The system automatically processes images, extracts their feature factors, and maintains the feature factor index library, eliminating the need for complex manual index management while improving sharing efficiency.

AI summary
A thumbnail-based image display method and terminal, where the method includes displaying a thumbnail on a screen, performing feature extraction on the thumbnail to obtain a feature factor of the thumbnail, displaying prompt information on the screen when the feature factor of the thumbnail is matched with a feature factor in a feature factor index library, where the feature factor index library indicates correspondences among feature factors and image storage addresses, obtaining an original image obtaining request, and displaying the original image on the screen based on the original image obtaining request. According to the method and terminal, feature indexes are created for all images in memories and buffers of all applications and in an image library, and an original high-resolution image is found using a feature factor of a thumbnail, thereby implementing high-definition image sharing between different applications.
