Multi-Camera Surround Video Recording with Dynamic Angle Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video recording technologies limit user interaction and angle selection during playback, as users cannot dynamically change the viewing angle of a scene while watching a film, and multiple camera angles are often recorded sequentially rather than simultaneously, creating limitations in immersive 3D experiences.
Innovation Solution
A system utilizing multiple Image Acquisition Devices (IADs) to record a scene from different angles simultaneously, with each IAD's image stream uniquely identified and selectable by the user in real-time, allowing dynamic angle changes and 3D effects by combining and processing independent image streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used to record from different angles, then user viewing angle selection and 3D experience are improved, but system complexity and equipment requirements worsen
Solution Approach 1:
The system segments the video recording function into multiple independent camera units, each capturing a specific angle. This allows the complex task of multi-angle recording to be divided into manageable independent components that can be selectively activated and processed separately, enabling user viewing angle selection without requiring all cameras to operate simultaneously at full complexity.
Solution Approach 2:
The patent implements a universal playback system that can handle multiple camera angles and 3D content through a single integrated platform. The system is designed to process and display various viewing angles (including left eye, right eye, and intermediate angles) using the same hardware infrastructure, making the complex multi-camera system manageable through standardized universal processing.
2Device complexity
If multiple camera angles are recorded sequentially, then equipment requirements are reduced, but user interaction and dynamic angle selection capability worsen
Solution Approach 1:
The system performs preliminary action by pre-recording multiple camera angles simultaneously during the filming process. This advance preparation of all possible viewing angles eliminates the need for sequential recording during playback, enabling users to dynamically switch between angles in real-time without requiring complex equipment reconfiguration or time-consuming sequential captures.
Solution Approach 2:
The patent implements dynamic angle selection capability where users can interactively change viewing angles during playback. The system dynamically switches between pre-recorded camera streams based on user input, allowing real-time angle changes without physical camera movement or repositioning, thus maintaining ease of operation while providing versatile viewing options.
3Adaptability or versatility
If simultaneous multi-angle recording is implemented, then user engagement and 3D experience are improved, but recording time and production efficiency worsen
Solution Approach 1:
The patent merges multiple camera recording operations into a single coordinated simultaneous recording process. By combining the capture of multiple angles into one unified recording session rather than requiring separate takes for each angle, the system achieves improved 3D experience and viewing angle versatility without proportionally increasing total production time, as all angles are captured during the same performance or event.
Data Source
AI summary
A method and a system are disclosed including multiple Image Acquisition Devices (IAD), such as cameras, simultaneously, consecutively, or independently filming a scene, each IAD having a known position with respect to each of the other IADs. Each image data stream obtained from each IAD may be uniquely identified, by the position of the IAD or by a unique identifier, to allow selective real-time display and/or playback of each individual image data stream under the control of a user. Depending on the position of an IAD, the image data stream collected by the IAD represents a corresponding viewing angle to the user. Thus, the user may dynamically select a different viewing angle for the same scene by selecting a corresponding image stream during real-time viewing and/or playback. In various embodiments, multiple image streams of the same scene may be selected and viewed simultaneously to provide a 3-Dimensional effect or other visual effects.
