Composite Thumbnail for Multi-Document Content Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiency in identifying and accessing the content of multiple digital documents obtained as search results, as they need to select and open each thumbnail image individually, which is a cumbersome process.
Innovation Solution
An information processing system that extracts a predetermined page from each digital document, generates a thumbnail image representing a set of these pages, and allows users to display the pages in an enlarged size upon input, enabling easier content identification and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user selects each thumbnail image individually to view digital document content, then the user can access the content of each document, but the operation process becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges multiple thumbnail images representing different digital documents into a single composite thumbnail image. This composite thumbnail displays multiple pages from different documents simultaneously, allowing users to view and compare content from multiple documents without individually selecting each thumbnail, thus resolving the contradiction between content identification accuracy and operation simplicity
Solution Approach 2:
The patent transitions from a one-to-one mapping (one thumbnail per document) to a many-to-one mapping (multiple thumbnails in one composite image). This dimensional change in the thumbnail structure allows users to access multiple document contents through a single selection, improving operational efficiency while maintaining content identification capability
2Loss of information
If multiple digital documents are displayed as individual thumbnail images in a list, then each document can be identified separately, but the user cannot efficiently compare or identify content across multiple documents
Solution Approach 1:
By combining multiple document thumbnails into a single composite thumbnail image that displays pages from multiple documents simultaneously, the system maintains full content visibility while dramatically improving document access efficiency. Users can compare and identify content across multiple documents in one view rather than sequentially opening each document
Solution Approach 2:
The composite thumbnail image segments and displays multiple document pages in an organized grid or array format within a single image. This segmentation allows users to visually distinguish and access specific document content while benefiting from the consolidated view, thus improving productivity without sacrificing content visibility

AI summary
An information processing system includes a processor configured to: extract, among one or more pages forming each of plural digital documents which are obtained as results of conducting a search by using a specified search condition, a predetermined page which is preset for each of the plural digital documents; perform control to generate a first image representing a set of the extracted predetermined pages of the respective digital documents and to display the first image on a display; and perform control, in response to a first input operation performed on the first image by a user, to display a second image, which represents the extracted predetermined pages, in an enlarged size on the display so that a display size of the second image becomes larger than a display size of the first image.
