Image Processing Device Tunnel Luminance Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques experience delays in outputting recognizable images when luminance changes significantly, such as when a vehicle enters or exits a tunnel, leading to potential blackening or halation issues.
Innovation Solution
An image processing device that acquires outside information and luminance data to rapidly switch between combined and uncombined images based on predetermined luminance thresholds, ensuring timely adjustment of image output to maintain image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image combination is started after luminance becomes equal to or less than a predetermined value, then image quality is improved, but output delay occurs with respect to luminance changes
Solution Approach 1:
The system starts the image combination process in advance based on outside information (such as tunnel detection) before the luminance actually drops below the threshold. This preliminary action ensures that the combined image is ready when needed, eliminating output delay while maintaining image quality.
Solution Approach 2:
The system dynamically switches between two operating modes: using outside information to trigger image combination when entering low-luminance areas, and using real-time luminance threshold detection for other conditions. This dynamic approach optimizes both response time and image quality根据不同场景.
2Reliability
If long time is taken for image processing, then image combination quality is improved, but combined image is output with delay
Solution Approach 1:
By initiating the image combination process in advance based on outside information before the luminance threshold is actually reached, the system prepares the combined image during the transition period. This eliminates the trade-off between processing time and output speed, as the processing completes just in time for immediate output.
3Loss of time
If image combination is performed in real-time, then output delay is reduced, but image quality may deteriorate under low luminance
Solution Approach 1:
The system proactively starts image combination before luminance drops, ensuring both timely output and high quality. The advance triggering based on outside information provides sufficient processing time while guaranteeing the combined image is ready immediately when luminance changes occur.
Solution Approach 2:
The system uses outside information as feedback to anticipate luminance changes and adjust the image combination timing accordingly. This feedback mechanism allows the system to optimize both processing quality and output timing by acting on predictive information rather than waiting for luminance to actually change.
