Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are deployed to monitor a scene, then the monitoring coverage is improved, but the installation and adjustment workload increases
Solution Approach 1:
The patent combines multiple camera functions (wide-field monitoring and narrow-field high-definition capture) into a single integrated camera device. This merging eliminates the need for multiple separate cameras, reducing installation and adjustment workload while maintaining comprehensive monitoring coverage.
Solution Approach 2:
The single camera device performs multiple functions: wide-field scene monitoring, narrow-field target capture, face recognition, and track information generation. This multi-functionality replaces what previously required multiple specialized cameras, simplifying deployment while achieving the same monitoring objectives.
2Area of stationary object
If multiple cameras are used for scene monitoring, then the monitoring coverage is improved, but the server performance requirement increases
Solution Approach 1:
By merging multiple camera functions into one device, the patent reduces the total number of video streams and data packets that the server must process. The single camera generates consolidated track information and alarm data, lowering server computational requirements compared to processing data from multiple separate cameras.
Solution Approach 2:
The camera performs preliminary processing operations (face recognition, target detection, track information generation) locally before transmitting data to the server. This extraction of processing functions from the server reduces the computational burden on the server while maintaining comprehensive monitoring coverage.
3Area of stationary object
If multiple cameras are deployed, then the monitoring coverage is improved, but the monitoring cost increases
Solution Approach 1:
The patent merges the functionality of multiple cameras into a single device, directly reducing the quantity of hardware equipment needed. This consolidation lowers monitoring costs by eliminating redundant camera units while maintaining the same monitoring coverage area.
Solution Approach 2:
The single camera device provides universal functionality that replaces multiple specialized cameras, reducing overall system cost. The device performs wide-field monitoring, narrow-field capture, and analysis functions that previously required separate equipment, thereby reducing monitoring costs while achieving comprehensive coverage.

AI summary
A method, apparatus and system for video display and a camera are disclosed. The camera includes one wide-field lens assembly and a wide-field sensor corresponding to the wide-field lens assembly; at least one narrow-field lens assembly and narrow-field sensor corresponding to the narrow-field lens assembly, wherein an angle of view of the wide-field lens assembly is greater than an angle of view of the narrow-field lens assembly, and for a same target, a definition of the wide-field sensor is smaller than that of the narrow-field sensor; and a processor configured for performing human body analysis on the wide-field image and performing face analysis, head and shoulder analysis or human body analysis on at least one frame of narrow-field image. The methods, apparatuses and systems can reduce the workload of installing and adjusting the cameras during monitoring, the performance requirements for the server, and monitoring costs.
