Vehicle Camera Mirror Views With Dynamic Resolution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles rely on rear-view and side mirrors for rear and side visibility, which can be limited in terms of field of view and clarity, especially when changing lanes or reversing, and may not provide adequate information for safe operation.
Innovation Solution
A system using cameras and displays to capture and present rear and side views of a vehicle, with adjustable resolution and field of view based on vehicle operation and driver input, allowing for enhanced visibility and safety by providing video data on dedicated displays positioned to mimic mirror locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rear-view and side mirrors are used, then the vehicle structure is simple and cost-effective, but the field of view and image clarity are limited
Solution Approach 1:
The patent replaces conventional mechanical mirrors with an electronic vision system comprising cameras, processors, and display devices. This substitution enables superior image clarity and multiple view angles while maintaining reasonable system complexity through integrated control and processing units.
2Measurement precision
If camera resolution is increased to improve visibility, then image clarity improves, but data processing requirements and system complexity increase
Solution Approach 1:
The system dynamically adjusts camera resolution based on operational context. During normal driving, standard resolution is used. When lane change or reversing maneuvers are detected through sensor inputs, the system automatically increases resolution to provide enhanced clarity, thereby balancing image quality with processing requirements.
3Reliability
If the field of view is expanded to reduce blind spots, then safety during lane changes improves, but image detail and resolution may be compromised
Solution Approach 1:
The system segments the visual field into multiple zones captured by different cameras. A wide-angle camera provides overall situational awareness for safety, while additional cameras or zoom capabilities focus on specific regions of interest. This segmentation allows simultaneous achievement of broad field of view and detailed image capture.
Solution Approach 2:
The system captures excessive visual information beyond what is immediately necessary, then processes and prioritizes it. During lane change maneuvers, the system captures extended side views and selectively enhances resolution for relevant areas, providing both comprehensive coverage and sufficient detail.
4Loss of information
If multiple displays are used to present different views, then driver awareness improves, but device complexity and cost increase
Solution Approach 1:
The system employs a multi-functional display architecture where a single display device can present multiple camera feeds, adjustable view angles, and contextual information. The display serves universal functions including rear-view, side-view, navigation guidance, and warning notifications, thereby improving driver awareness without proportionally increasing system complexity.
Data Source
AI summary
A system for capturing and presenting views of a vehicle. In an example embodiment, the system captures video data rearward and along a side of the vehicle and/or behind the vehicle. The system includes video cameras for capturing video data at one or more resolutions and in one or more fields-of-view. The displays present the video data to the driver for use during operation of the vehicle. The displays present the video data at one or more resolutions. The resolution of capture and/or display may be in accordance with an operating mode of the vehicle, such as turning, direction of travel and/or driver selection.
