Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video switching is performed between multiple cameras without content matching, then video switching can be performed simply, but the switching appears unnatural and discontinuous
Solution Approach 1:
The system performs preliminary content analysis of videos from multiple cameras before switching occurs. By analyzing and identifying content elements in advance, the system can determine appropriate switching timing and conditions, ensuring natural transitions without requiring complex real-time coordination during the actual switching moment.
Solution Approach 2:
The system continuously monitors and compares content elements across different camera videos, using this feedback to determine optimal switching conditions. The content analysis results provide feedback that guides the switching decision, ensuring that transitions occur only when content continuity is maintained, thus achieving natural switching appearance.
2Reliability
If content analysis and angle adjustment are performed to ensure smooth transitions, then video switching naturalness is improved, but system complexity increases
Solution Approach 1:
The system segments the video content analysis into distinct elements such as objects, actions, and spatial relationships. By breaking down the complex task of content matching into manageable segments, the system can process each element independently using simpler algorithms, reducing overall system complexity while maintaining transition quality.
Solution Approach 2:
The system adjusts the angle of view parameter of cameras based on content analysis results. By changing this single key parameter rather than requiring complex coordinated movements of multiple cameras, the system achieves smooth transitions with relatively simple control mechanisms, balancing naturalness improvement with complexity management.
3Reliability
If the second camera changes angle of view to match content, then video switching discontinuities are reduced, but the time required for transition preparation increases
Solution Approach 1:
The system performs content analysis and angle adjustment in advance before the actual video switching moment. By preparing the second camera's angle of view beforehand based on pre-analyzed content, the system minimizes the time required during the transition itself, as the camera is already positioned appropriately when switching occurs.
Solution Approach 2:
The system maintains continuous content analysis and angle adjustment operations leading up to the switching moment, ensuring that the useful action of preparing the second camera is ongoing rather than interrupted. This continuous preparation reduces the perceived transition time by keeping the system in a state of readiness without unnecessary delays.

AI summary
A control apparatus identifies content of a video. The control apparatus determines a video cutting type indicating a relationship between videos at a time of switching video from a first video captured by a first image capturing device in accordance with a result of identifying content of the first video. The control apparatus determines whether a result of identifying content of a second video captured by a second image capturing device satisfies a condition corresponding to the video cutting type. The second image capturing device captures the second video while changing an angle of view. The control apparatus determines that the first video can be switched to the second video based on a result of the determination that the condition is satisfied.
