Dual Camera Video Processing for Simultaneous Multi-Angle Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video processing methods are limited in diversity, restricting subsequent presentation and editing options, which hampers user experience, especially when capturing scenery and the photographer simultaneously.
Innovation Solution
A video processing method and apparatus that utilizes cameras on both sides of a terminal for simultaneous video recording, allowing for flexible video presentation and editing by generating multiple video streams and timelines for synchronized audio and video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras on both sides of the terminal are used for simultaneous video recording, then video recording diversity and flexibility are improved, but device complexity increases
Solution Approach 1:
The patent divides the video recording system into two independent camera modules (first camera on first side, second camera on second side) that operate simultaneously but independently. Each camera captures video streams separately, and the system segments the processing by handling each stream through dedicated playback and editing pathways, thereby managing complexity through modular organization while achieving diverse recording capabilities
Solution Approach 2:
The terminal device is designed with multi-functional capability by enabling both cameras to serve multiple purposes: they can record simultaneously from different angles, provide flexible presentation options (front view, back view, or combined), and support various editing modes. This universal design allows a single device to perform diverse video recording functions without requiring additional specialized hardware
2Adaptability or versatility
If multiple video streams are generated from simultaneous camera recording, then editing flexibility is improved, but data processing complexity increases
Solution Approach 1:
The system performs preliminary organization of multiple video streams during the recording phase by maintaining separate first and second video streams with associated timelines. This pre-structured data organization enables flexible editing later without requiring complex real-time processing, as the streams are already segmented and timestamped for easy manipulation
Solution Approach 2:
The patent creates separate copies of video streams from each camera, allowing independent processing and editing of each stream. These copied streams can be manipulated separately (e.g., switching between them, editing one without affecting the other) reducing the complexity of handling multiple sources simultaneously while maintaining full editing flexibility

AI summary
The disclosure provides techniques for facilitating video creations. The techniques comprise turning on a first camera on a first side of a terminal; turning on a second camera on a second side of the terminal; capturing, by the first camera, a first video; capturing, by the second camera, a second video; displaying the first video and the second video concurrently, wherein the displaying further comprises displaying the first video in a first area and the second video in a second area during a first time period, and in response to a first instruction to switch video content, displaying the second video in the first area and the first video in the second area during a second time period; and creating a timeline including the first time period, the second time period, and a time stamp of the video content switch in the first area.
