Rear-View Image Processing for Dynamic Blind-Spot Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems for vehicles do not adequately address the need to switch display modes during normal driving to prevent vehicles from entering blind spots, such as during overtaking, merging, or encountering emergency vehicles, thereby increasing the risk of accidents.
Innovation Solution
An image processing device with a processor that acquires video from a rear-facing imaging device, detects predetermined targets, and adjusts the display range on the display unit to include these targets, expanding or contracting the displayed area based on detected vehicle actions or conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display mode is switched only when departure manipulation is detected, then the display switching is simple and easy to operate, but the driver awareness of potential hazards in blind spots is insufficient
Solution Approach 1:
The system performs preliminary detection of vehicles in blind spots before the driver needs to check. The display control unit proactively switches to wide-angle display when a vehicle is detected in the blind spot area, before the driver initiates any departure manipulation, ensuring hazard awareness is provided in advance
Solution Approach 2:
The system continuously monitors the rear video feed and provides feedback to the display control unit about detected vehicles. When a vehicle is detected in the blind spot region, the system automatically switches the display mode to wide-angle, creating a closed-loop feedback mechanism that enhances driver awareness without requiring manual intervention
2Measurement precision
If the display shows a narrow field of view, then the image quality and detail are improved, but the coverage area and blind spot detection capability deteriorate
Solution Approach 1:
The display control unit dynamically adjusts the field of view between narrow and wide angles based on detected conditions. During normal driving, the narrow field of view is displayed for high image quality, but when a vehicle is detected in the blind spot, the system automatically switches to wide-angle display to expand coverage area and provide comprehensive hazard awareness
Solution Approach 2:
The system changes the display parameter (field of view angle) based on detected conditions. The display control unit switches between narrow and wide field of view modes by adjusting the display parameters, allowing the system to optimize between image quality and coverage area depending on the driving situation and detected hazards

AI summary
To implement an image processing device capable of improving rear visibility of a mobile object, the image processing device includes: an acquisition unit configured to acquire a video from an imaging device that generates images of a rear of a mobile object; a display control unit configured to cause a display unit to display a first range in the video acquired by the acquisition unit; and a detection unit configured to detect a predetermined target based on the video acquired by the acquisition unit. When the detection unit detects the predetermined target, the display control unit causes the display unit to display the video in a second range different from the first range.
