Multi-Camera System Frame Synchronization via Unique Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-camera systems lack the ability to efficiently switch between video feeds from multiple cameras captured at different angles in real-time, making it difficult for users to confirm and review specific moments or events captured by multiple cameras simultaneously.
Innovation Solution
A multi-camera system comprising a first and second camera apparatus and an information processing apparatus, where the processing circuitry sends control signals to assign unique identifiers to frames of captured videos, allowing seamless switching and playback of video frames between cameras, enabling users to confirm and review images captured by multiple cameras on a confirmation apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple camera videos are reproduced separately on cameras or imported into a personal computer, then the captured moving images can be viewed, but it is difficult to switch between video feeds from different angles in real-time and confirm specific moments efficiently
Solution Approach 1:
The patent combines multiple video feeds from different cameras into a single playback system. The playback apparatus receives video signals from multiple cameras and displays them simultaneously or switchably on one screen, allowing users to view and switch between different angles without importing files to multiple devices or manually managing separate playback sessions.
Solution Approach 2:
The playback apparatus serves multiple functions: it can display video feeds from any of the connected cameras, switch between different camera angles, pause and review specific moments, and handle multiple video sources simultaneously. This multi-functional device replaces the need for separate camera displays or complex personal computer file management workflows.
2Adaptability or versatility
If video files from multiple cameras are imported into a personal computer, then the files can be reproduced, but the system complexity and file management burden increase
Solution Approach 1:
The playback apparatus autonomously manages multiple video feeds by automatically receiving, processing, and displaying signals from multiple cameras. The system handles video synchronization, angle switching, and moment review functions without requiring users to manually import, organize, or manage video files on a personal computer, thereby reducing system complexity and user burden.
3Productivity
If real-time switching between multiple camera angles is implemented, then user experience improves, but the need for complex synchronization and frame matching increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing frame number associations between multiple cameras before playback. During video capture, the system records and stores the correspondence between frame numbers from different cameras, creating a synchronization map in advance. This preliminary frame matching eliminates the need for complex real-time synchronization calculations during playback, enabling smooth angle switching while maintaining operational efficiency.

AI summary
A multi-camera system, including a first camera apparatus, a second camera apparatus, and an information processing apparatus. The information processing apparatus includes a communication interface and processing circuitry. The processing circuitry is configured to receive a predetermined user input and in response to the predetermined user input, send, via the communication interface, a first control signal to the first camera apparatus that captures a first video, and send, via the communication interface, a second control signal to the second camera apparatus that captures a second video. The first control signal causes the first camera apparatus to assign first unique identifiers to frames of the first video captured by the first camera apparatus. The second control signal causes the second camera apparatus to assign second unique identifiers to frames of the second video captured by the second camera apparatus.
