Solution Overview

Problem

Existing technologies that hide vehicles exhibiting road rage behavior in the rear-view mirror prevent drivers from confirming the circumstances near the following vehicle, leading to stress.

Innovation Solution

An information processing device with a road rage detection portion, image processing portion, and display processing portion that processes rear images to display them on a display device, allowing occupants to confirm the rear side of the vehicle without stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the rear view is changed to hide the following vehicle exhibiting road rage behavior, then the driver's stress is reduced, but the driver cannot confirm the circumstances near the following vehicle

Engineering Contradiction:
ImprovestressVSAvoidcircumstances near following vehicle
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The rear view image is segmented into multiple regions: the following vehicle region is processed separately from other regions. The image processing portion selectively applies processing to specific areas (the following vehicle) while preserving other areas unchanged, allowing different information needs to be satisfied in different regions of the display

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different processing is applied to different parts of the rear view image. The following vehicle region receives stress-reducing processing (blurring, obscuring), while other regions maintain normal clarity. This local differentiation allows the driver to see circumstances in unaffected regions while the aggressive vehicle is hidden

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the following vehicle is completely hidden in the rear-view mirror, then the driver feels less stress, but it becomes impossible to monitor the following vehicle's actions

Engineering Contradiction:
Improvedriver's emotional stateVSAvoidmonitoring capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts the processing applied to the rear view based on real-time detection of road rage behavior. When road rage is detected, selective processing is applied; when not detected, the full rear view is displayed. This dynamic adaptation allows the system to balance stress reduction with monitoring needs based on actual conditions

Inventive Principle:
Principle #15Dynamics

AI summary

A solution is to detect whether a following vehicle detected in a rear image of a vehicle is exhibiting a road rage behavior, perform an image processing to the rear image of the vehicle if the following vehicle is exhibiting the road rage behavior; and display the processed image on a display device.
