Preview Image Generation for Content Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are limited in their ability to view preview images for content data as they can only access pre-prepared images, and if a preview image is not available, they cannot create one, restricting their freedom in image viewing and management.
Innovation Solution
An information processing apparatus and computer program that generates preview images, informs users why a preview image is not available, and allows users to instruct the creation of a preview image for content data that does not have one, provided certain conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If preview images are prepared in advance for all content data, then users can freely view preview images, but storage space is wasted and device complexity increases
Solution Approach 1:
The system performs preliminary actions by automatically generating preview images for content data that meets predetermined conditions (such as frequently accessed files or important documents) before users request them. This selective preliminary generation balances storage efficiency with user convenience, avoiding the need to pre-generate previews for all content.
Solution Approach 2:
The system applies different preview generation strategies to different content data based on local characteristics. High-priority content (e.g., frequently accessed files, important documents) receives automatic preview generation, while low-priority content does not. This localized approach optimizes storage space while maintaining user freedom for important content.
2Adaptability or versatility
If preview images are generated for all content data, then users can view any preview image, but device complexity and processing time increase
Solution Approach 1:
The system changes parameters such as preview image resolution, format, and generation quality based on content characteristics and user needs. For example, text documents may receive low-resolution previews while images receive high-resolution previews. This parameter adaptation reduces processing complexity while maintaining versatility.
Solution Approach 2:
Instead of generating complete high-quality previews for all content, the system generates partial or lower-quality previews for content that doesn't require full processing. This partial action approach reduces device complexity and processing time while still providing sufficient preview functionality for most use cases.
3Quantity of substance
If no preview images are stored, then storage space is optimized, but users cannot view or create preview images
Solution Approach 1:
The system enables users to self-service by allowing them to request preview image generation on-demand for content data that doesn't have pre-generated previews. When users encounter content without previews, they can trigger generation through simple operations, and the system automatically creates the preview and stores it for future use. This maintains storage efficiency while preserving user freedom.
Solution Approach 2:
The system implements feedback mechanisms where users can provide input when preview images are unavailable (e.g., clicking a generation button). The system then processes this feedback by generating the requested preview and confirming completion to the user. This feedback loop maintains storage efficiency while ensuring users can obtain previews when needed.

AI summary
An information processing apparatus includes a processor configured to generate a preview image used for previewing content data, present a reason why there is no preview image, in a case where an operation related to display of the preview image is received for the content data which does not have the preview image, and allow reception of a preview image creation instruction from a user, for content data which does not have the preview image and satisfies a first condition.
