Vehicle Image Processing Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems in vehicles fail to promptly notify drivers of anomalies, leading to potential safety risks due to the lack of immediate awareness during switching from main to sub-image processing sections, resulting in delayed detection of malfunctions.
Innovation Solution
An image processing apparatus with an anomaly detection section that outputs a signal indicating anomalies, allowing the system to perform image processing independently of the main command signal when an anomaly is detected, and selecting between normal and anomaly-related image signals for immediate display to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a backup system with main and sub-image processing sections is implemented, then reliability is improved, but response time deteriorates due to switching delay
Solution Approach 1:
The anomaly detection section performs preliminary detection of anomalies in the main image processing section by monitoring its output signals. When an anomaly is detected, the system immediately switches to displaying anomaly information without waiting for the sub-image processing section to take over, thus eliminating the switching delay while maintaining reliability
Solution Approach 2:
The anomaly detection section acts as an intermediary between the main image processing section and the display section. It monitors the main section's output and directly generates anomaly notification signals that can be displayed immediately, bypassing the need for switching to a backup section and thus reducing response time
2Reliability
If switching from main to sub-image processing section is implemented, then system redundancy is improved, but information transmission capability deteriorates during transition
Solution Approach 1:
The anomaly detection section continuously monitors the output signals from the main image processing section and provides feedback about the system's operational status. When anomalies are detected, this feedback triggers immediate anomaly information display, ensuring that no information is lost during the transition period and maintaining both redundancy and information integrity

AI summary
An image processing apparatus has a main processing section that outputs an image processing command signal; an anomaly detection section that detects an anomaly in the main processing section, outputting an anomaly information output signal; an image processing section that outputs a first image signal when the main processing section is in normal operation and that outputs a second image signal when an anomaly has occurred in the main processing section; and an image selection section that selects either the first image signal or the second image signal on the basis of the anomaly information output section.
