Vehicle Camera Setting Arbitration for Multi-Function Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle camera systems are unable to dynamically adjust camera settings to prioritize different image processing functions, leading to sub-optimal performance for secondary image processing tasks such as accident analysis due to settings optimized for primary safety-related operations.
Innovation Solution
A system and method for sharing camera settings among multiple image processing components, where a higher priority is applied to safety-critical functions, allowing the first image processing component to configure camera settings and relinquish control to the second component for accident-related functions, utilizing an access arbitrator to manage access and settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If camera settings are optimized for safety-critical image processing (high frame rate, focused field-of-view), then safety monitoring performance is improved, but accident analysis performance deteriorates (low resolution, narrow field-of-view)
Solution Approach 1:
The camera settings are made dynamic rather than static. The system switches between different camera configurations based on operational context: during normal driving, settings are optimized for safety monitoring (high frame rate, focused FOV), while during accident events, settings switch to optimize for accident analysis (high resolution, wide FOV). This dynamic adaptation resolves the contradiction by allowing optimal settings for each function at different times.
Solution Approach 2:
The system changes camera parameters (frame rate, field-of-view angle, resolution) based on operational mode. By adjusting these parameters dynamically according to whether the system is in safety-monitoring mode or accident-recording mode, the contradiction between optimized safety performance and accident analysis quality is resolved.
2Measurement precision
If camera settings are optimized for accident analysis (high resolution, wide field-of-view), then accident documentation quality is improved, but safety monitoring performance deteriorates (low frame rate, narrow effective field-of-view)
Solution Approach 1:
The camera system dynamically adjusts its configuration based on operational requirements. When accident analysis is the priority, settings switch to high resolution and wide field-of-view. When safety monitoring is critical, settings switch to high frame rate and focused field-of-view. This temporal separation of optimization goals resolves the contradiction.
3Device complexity
If a single camera serves multiple image processing functions, then device complexity is reduced, but image processing performance for each function deteriorates due to conflicting settings requirements
Solution Approach 1:
Rather than using multiple static cameras for different functions, the system uses a single camera with dynamic reconfigurable settings. The camera alternates between safety-monitoring configuration and accident-recording configuration based on operational context, maintaining single-device simplicity while achieving optimal performance for each function when needed.
Solution Approach 2:
A single camera unit is designed to perform multiple functions (safety monitoring and accident analysis) by dynamically adjusting its parameters. This multi-functionality approach reduces device complexity while maintaining performance through context-dependent configuration switching.

AI summary
The disclosure is generally directed to systems and methods for sharing a video feed of a camera among multiple image processing components in a vehicle. A first priority may be applied to a first image processing component that performs a first image processing function. A second priority that is lower than the first priority, is applied to a second image processing component that performs a second image processing function. The first function may be deemed more important than the second function due to various reasons. Consequently, the first image processing component is offered priority to apply a first set of camera settings on the camera. The second image processing component may prefer to apply a different set of camera settings for executing the second image processing function. An access arbitrator allows the second image processing component to do so when the first image processing component relinquishes control of the camera.
