Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a controlled process for displaying digital content items used to form virtual viewpoint images, particularly in relation to ownership and user information management.
Innovation Solution
An information processing apparatus that acquires and manages user information and material data recorded on a blockchain, allowing users to select and display virtual viewpoint images based on owned material data and virtual viewpoint information, including the ability to manipulate virtual camera positions and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple material data owned by different users are output and made available for selection, then the versatility and user choice are improved, but the complexity of ownership management and system coordination increases
Solution Approach 1:
The patent segments material data by ownership, organizing multiple material data from different users into distinct categories. The system separates ownership information from material data content, allowing independent management of each. This segmentation enables the system to handle multiple owners' data without creating a monolithic complex structure, as each user's material data can be managed separately while still being accessible for virtual viewpoint image generation.
Solution Approach 2:
The patent introduces an intermediary information processing apparatus that mediates between multiple users and the virtual viewpoint image generation process. This intermediary manages ownership information, coordinates material data selection, and controls the generation process based on user permissions. By positioning this intermediary layer, the system handles ownership complexity centrally rather than requiring direct coordination between all users, thus reducing overall system complexity while maintaining versatility.
2Ease of operation
If users can select and control material data used in virtual viewpoint image formation, then user control and content protection are improved, but the complexity of the display control process increases
Solution Approach 1:
The patent implements preliminary action by having users pre-select and designate specific material data to be used in virtual viewpoint image generation before the actual generation process. Users can designate their owned material data in advance, and the system stores these designations. When generating virtual viewpoint images, the system automatically uses the pre-designated material data without requiring real-time user intervention, thus simplifying the control process while maintaining user control and content protection.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system provides information to users about which material data is being used or can be used in virtual viewpoint image generation. This feedback loop allows users to understand the relationship between their designated material data and the generated images, enabling informed control decisions. The system monitors and reports on material data usage, ownership status, and generation results, creating a transparent control process that balances user autonomy with system automation.
