Information Processing Device Thumbnail Generation via Pre-Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in swiftly displaying icon images and transmitting only user-selected data, especially when dealing with formats like PDF that are hard to process, leading to privacy and security concerns due to unnecessary data uploads.
Innovation Solution
A system comprising a display controlling section, transmission controlling section, obtainment controlling section, and storage controlling section that converts and stores reduced-size image data associated with targeted data, allowing for efficient display of icon images and secure transmission of only selected data, using a conversion server to convert PDF files into JPEG format for processing by mobile terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all data corresponding to icon images are uploaded to server each time for conversion, then thumbnail display is enabled for hard-to-process formats, but processing time increases and user privacy/security is compromised
Solution Approach 1:
The system pre-converts data to formats suitable for thumbnail generation and stores the converted data and thumbnails in advance. When a user needs to display icon images, the system retrieves pre-converted data and pre-generated thumbnails from storage, eliminating the need to upload and convert all data again, thus significantly reducing processing time while maintaining the ability to handle hard-to-process formats
Solution Approach 2:
The system extracts only the necessary data for thumbnail generation from the original data set. Instead of uploading all data corresponding to icon images, the system identifies and extracts only the minimal required information, converts it, and stores it separately. This reduces the amount of data transmitted and processed, addressing the time loss issue while preserving the capability to display thumbnails for various formats
2Adaptability or versatility
If all data is uploaded to server for conversion, then thumbnail display capability is achieved, but unintended data transmission occurs causing privacy and security problems
Solution Approach 1:
The system extracts and transmits only the minimal necessary data required for generating thumbnails, rather than uploading all data. By identifying only the essential information needed for icon image generation and transmitting solely that, the system enables thumbnail display capability while minimizing the exposure of sensitive information, thus addressing privacy and security concerns
Solution Approach 2:
The system creates a copy of the necessary data for conversion and thumbnail generation, separate from the original data storage. This copied data is what gets transmitted to the server and stored locally, allowing the system to maintain the ability to generate thumbnails while keeping the full original data secure and preventing unintended transmission of sensitive information

AI summary
A nontransitory storage medium storing an information processing program to be executed by an information processing device, the program being designed to have the device function as: a display controlling section for controlling a display portion to display icon images; a transmission controlling section for controlling a transmitting portion to transmit user-selected targeted data among data corresponding to the icon images; an obtainment controlling section for controlling an obtaining portion to obtain converted data created by an external device based on the targeted data; and a storage controlling section for storing reduced-size image data created using the targeted data, into a storage portion such that the reduced-size image data is associated with the targeted data. For each data with which the reduced-size image data is associated, the display portion displays a reduced-size image corresponding to the reduced-size image data as an icon image.
