Virtual Camera Path Interpolation with Change Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating camera paths that align with user intent are burdensome, requiring significant effort and repetition in setting key frames to prevent abrupt changes in virtual viewpoint parameters, increasing user workload.
Innovation Solution
An information processing apparatus that generates virtual camera paths by interpolation using key frames, including a designation unit for user input, a specifying unit for calculating the number of frames between key frames, a change amount specifying unit for determining parameter changes per unit of time, and a notification unit to inform users of these changes, allowing for easier alignment with user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If key frames are discretely selected and automatic interpolation is performed, then the quality of virtual viewpoint content is improved, but the user burden related to setting virtual viewpoints increases
Solution Approach 1:
The system calculates and notifies the amount of change per unit time of virtual camera parameters between key frames, providing feedback to the user about the interpolation results. This allows users to understand the effect of their key frame settings without repeatedly performing preview displays, thereby reducing operational burden while maintaining content quality.
Solution Approach 2:
The system performs preliminary calculation of the amount of change in virtual camera parameters between key frames before the user finalizes the settings. By notifying users of these changes in advance, users can make informed decisions about key frame placement without needing to repeatedly preview the entire content, thus reducing the number of iterative operations required.
2Reliability
If preview display is performed repeatedly to confirm parameter changes, then the alignment with user intent is improved, but the time and effort required increases
Solution Approach 1:
The notification unit provides immediate feedback to users about the amount of change in virtual camera parameters between key frames. This feedback mechanism allows users to confirm whether the interpolation aligns with their intent without performing time-consuming preview displays, significantly reducing the time and effort required while maintaining alignment with user intent.
Solution Approach 2:
The system replaces the mechanical process of repeatedly performing preview displays with an information-based notification system that calculates and presents the amount of parameter change. This substitution eliminates the need for repeated rendering and playback operations, reducing time consumption while providing sufficient information for users to verify alignment with their intent.
3Manufacturing precision
If correction of key frames is repeated to prevent abrupt changes, then the quality of camera path is improved, but the operational complexity increases
Solution Approach 1:
The system notifies users of the amount of change in virtual camera parameters between key frames, providing feedback that helps users understand whether abrupt changes will occur. This enables users to make appropriate adjustments to key frame settings based on the notified information, improving camera path quality without requiring complex repeated correction operations.
