Virtual Viewpoint Image Display With NFT-Based Content Rights Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual viewpoint image generation techniques struggle to effectively protect the rights of digital content creators while allowing users to enjoy and interact with digital content, particularly in scenarios where multiple objects or players are involved, leading to difficulties in judging which content to purchase and generating images that do not include all relevant objects.
Innovation Solution
A system that utilizes non-fungible tokens (NFTs) on a blockchain to assign rights to digital content, combined with an image processing apparatus that generates virtual viewpoint images based on content data, including appearance and position information, and controls display based on user ownership, allowing for controlled and enhanced interaction with digital content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual viewpoint images are generated using multiple digital content objects, then the completeness and richness of the displayed content is improved, but it becomes difficult for users to judge which content to purchase and the system complexity increases
Solution Approach 1:
The patent segments digital content into individual purchasable objects (players, characters, items) with distinct ownership rights. Each object can be independently purchased and managed, allowing the system to display multiple objects while maintaining clear ownership boundaries. This segmentation resolves the contradiction by enabling complete content display through multiple independent units rather than requiring complex integrated content management.
Solution Approach 2:
The patent implements preliminary action by establishing blockchain-based ownership records before content display. Ownership rights are predetermined and verified through NFTs, allowing the system to automatically determine which objects to display without complex real-time judgment logic. This preliminary establishment of rights simplifies the display process while ensuring complete and accurate content presentation.
2Reliability
If blockchain technology is implemented to protect digital content rights, then the security and reliability of content ownership is improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer that mediates between content creators and users. The blockchain network verifies and records ownership rights without requiring the displaying system to implement complex security protocols. This intermediary approach maintains high reliability of ownership verification while keeping the display system relatively simple, as it only needs to query blockchain for ownership information.
3Ease of operation
If simplified display is used for digital content, then the ease of operation and user interface simplicity is improved, but the ability to fully enjoy and interact with detailed content is reduced
Solution Approach 1:
The patent implements dynamic display adjustment based on user interactions and ownership status. The system can switch between simplified overview displays and detailed content views, allowing users to enjoy comprehensive content details when needed while maintaining simple operation modes for routine interactions. This dynamic adaptability resolves the contradiction by providing both simplicity and detail quality according to different usage contexts.

AI summary
An information processing apparatus (4) is provided. The apparatus obtains (S207) content data of a first digital content related to a first object to which a user has a right, and content data of a second digital content related to a second object to which the user does not have a right. The apparatus verifies (S208) whether the user has rights to the first digital content and the second digital content. The apparatus generates (S210) a virtual viewpoint image showing the first object and the second object. A display mode of the first object differs from a display mode of the second object.
