Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used for presentation/video conferencing/live broadcasting, then the communication performance is improved, but the ease of operation deteriorates due to difficulty in finding and switching between camera setting pages
Solution Approach 1:
The patent introduces a camera switching interface that acts as an intermediary between the user and multiple cameras. This interface consolidates control over multiple cameras in a single location, eliminating the need to navigate through different camera setting pages. The switching interface displays thumbnails of all cameras and allows direct selection, thereby improving ease of operation while maintaining multi-camera versatility.
2Adaptability or versatility
If camera setting pages are changed during presentation/video conferencing/live broadcasting, then the adaptability is improved, but the loss of time increases due to inability to quickly switch cameras
Solution Approach 1:
The patent implements preliminary action by displaying thumbnails of all available cameras in advance within the camera switching interface. This allows users to preview and familiarize themselves with different camera views before actually switching. The interface pre-loads and organizes camera options, so when switching is needed, users can immediately select from the displayed thumbnails without navigating to different setting pages, thereby reducing camera switching time while maintaining flexibility.
3Adaptability or versatility
If users need to interact with speaker or environment during presentation/video conferencing/live broadcasting, then the adaptability is improved, but the loss of time increases due to need to walk around and cannot timely switch cameras
Solution Approach 1:
The camera switching interface serves as a mediator that enables users to switch cameras without leaving their current position or interrupting their interaction with the speaker or environment. By consolidating camera control in an accessible interface, users can quickly switch between cameras while remaining engaged in their presentation or conversation, thus maintaining adaptability for interaction while minimizing response time loss.
4Adaptability or versatility
If camera switching is enabled during presentation/video conferencing/live broadcasting, then the adaptability is improved, but the device complexity increases due to multiple camera DMFT units and integrated DMFT unit
Solution Approach 1:
The patent applies merging by combining multiple camera DMFT units into a single integrated DMFT unit. Instead of having separate, independent DMFT units for each camera, the integrated unit consolidates the media foundation transform functions for all cameras into one component. This reduces device complexity by eliminating redundancy while maintaining the ability to support multiple cameras simultaneously, thus achieving multi-camera adaptability without proportionally increasing complexity.

AI summary
An electronic device capable of performing multi-camera intelligent switching and a multi-camera intelligent switching method thereof are provided. The electronic device includes a plurality of camera device media foundation transform (camara DMFT) units, an integrated DMFT unit and a mix camera agent. Each of the camera DMFT units is connected to one of a plurality of cameras. The integrated DMFT unit is serially connected to one of the camera DMFT units. The mix camera agent is connected to the cameras. The mix camera agent is used for obtaining a switching notification signal. The integrated DMFT unit switches a serial path between the integrated DMFT unit and one of the camera DMFT units according to the switching notification signal.
