Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle video processing systems face challenges in maintaining consistent image quality for both rear and forward views, and in efficiently managing video processing and transmission between cameras and display units, leading to increased costs and component complexity.
Innovation Solution
A video processing device and system that includes a first imaging device, first and second display devices, and a video processing unit capable of receiving, processing, and transmitting videos from multiple cameras to different display units, allowing independent operation of control blocks to ensure continuous video display and alignment of image quality across various uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single video processing system handles both rear and forward views, then system complexity is reduced, but image quality consistency becomes difficult to maintain
Solution Approach 1:
The video processing system is divided into separate control blocks: a first control block processes rear view video while a second control block processes forward view video. This segmentation allows each block to be optimized independently for its specific processing requirements, maintaining image quality consistency across different views while managing overall system complexity.
2Device complexity
If video processing and transmission is centralized, then component complexity is reduced, but reliability decreases due to single point of failure
Solution Approach 1:
The system is segmented into multiple independent control blocks that can operate autonomously. The first control block handles rear view processing while the second handles forward view processing, creating redundancy that improves reliability without significantly increasing overall component complexity.
Solution Approach 2:
Different processing parameters and methods are applied to different video streams based on their specific requirements. The system adjusts processing parameters dynamically for rear versus forward views, optimizing performance and reliability for each function while managing component complexity.
3Reliability
If separate control blocks are used for different video processing functions, then reliability and continuous operation are improved, but device complexity increases
Solution Approach 1:
The video processing system is divided into functionally independent control blocks that can operate continuously without interfering with each other. This segmentation enables the system to maintain high reliability and continuous operation capability while keeping each control block's complexity manageable through clear functional separation.
