Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple videostreams are processed through a single image sensor and processor, then device complexity is reduced, but video quality and resolution deteriorate
Solution Approach 1:
The patent divides the video processing system into multiple independent image sensors and image processors, with each sensor-processor pair handling specific videostreams. This segmentation allows each processor to dedicate full computational resources to its assigned streams, maintaining high video quality while enabling parallel processing of multiple streams simultaneously.
Solution Approach 2:
The patent transitions from a single-threaded processing architecture to a multi-threaded parallel architecture by adding temporal and spatial dimensions to processing capacity. Multiple image sensors capture video simultaneously from different perspectives, and multiple image processors handle different streams in parallel, effectively adding dimensional capacity to resolve the quality-complexity contradiction.
2Manufacturing precision
If high resolution processing is applied to all videostreams, then video quality improves, but processing power requirements and costs increase
Solution Approach 1:
The patent applies different processing resolutions and qualities to different videostreams based on their specific requirements. Primary videostreams (field-of-view) receive high-resolution processing, while secondary videostreams (region-of-interest) may use optimized processing appropriate to their smaller size and specific use cases, thereby reducing overall processing power requirements while maintaining necessary video quality.
3Adaptability or versatility
If multiple image sensors and processors are used, then video quality and scalability improve, but device complexity increases
Solution Approach 1:
The patent designs the image sensors and processors as universal, multi-functional components that can handle different types of videostreams (primary/field-of-view and secondary/region-of-interest) interchangeably. Each image processor can process both types of streams, and the system can dynamically allocate resources based on conference needs, providing scalability without proportionally increasing complexity.
4Manufacturing precision
If separate processing chains are implemented for field-of-view and region-of-interest streams, then video quality is maintained, but processing time and system complexity increase
Solution Approach 1:
The patent performs preliminary actions by having image sensors continuously capture and pre-process video data into both primary (field-of-view) and secondary (region-of-interest) streams simultaneously. This preliminary processing ensures that both stream types are ready for immediate output without requiring sequential processing, thereby maintaining video quality while minimizing processing delays.
