Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera monitoring systems for vehicles lack the ability to dynamically adjust the display of captured images based on vehicle speed and environmental conditions, leading to suboptimal field of view for drivers, especially during high-speed travel or maneuvering.
Innovation Solution
A camera monitoring system comprising multiple cameras and an image processing device that adjusts the layout and orientation of captured images based on vehicle information and environmental data, allowing for adaptive display modes to enhance the driver's field of view by changing the shape, size, and arrangement of images displayed on a monitor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional optical mirror is used for monitoring, then the field of view is fixed and simple structure is maintained, but the adaptability to different vehicle speeds and conditions is poor
Solution Approach 1:
The patent applies dynamics by making the camera system adjustable based on vehicle conditions. The camera's angle of view and capturing direction are dynamically changed according to vehicle speed and traveling direction, transforming a static monitoring system into an adaptive one that responds to real-time driving conditions.
Solution Approach 2:
The patent implements parameter changes by modifying the camera's operational parameters (angle of view, capturing direction) based on vehicle speed and environmental conditions. This allows the system to adapt its monitoring characteristics to match different driving scenarios without changing the physical hardware configuration.
2Ease of operation
If the angle of view is decreased for high-speed travel, then the driver's field of view characteristics are complemented, but the monitoring coverage is reduced
Solution Approach 1:
The system dynamically adjusts the angle of view based on vehicle speed. During high-speed travel, the angle of view is decreased to match driver characteristics, while during low-speed travel, it is increased to provide broader monitoring coverage. This dynamic adjustment resolves the contradiction between driver comfort and monitoring coverage.
Solution Approach 2:
The camera monitoring system periodically adjusts its parameters based on changing vehicle conditions. The angle of view and capturing direction are continuously modified according to real-time speed and direction data, ensuring optimal performance across varying driving scenarios.
3Area of stationary object
If multiple cameras are used to improve monitoring coverage, then the field of view is enhanced, but the device complexity and cost increase
Solution Approach 1:
The patent makes a single camera perform multiple functions by enabling it to capture images in different directions and at different angles based on vehicle conditions. This multi-functionality allows the single camera to replace what would traditionally require multiple fixed cameras, reducing system complexity while maintaining comprehensive monitoring coverage.
Solution Approach 2:
By making the camera's capturing direction and angle dynamically adjustable, the system allows one camera to cover multiple monitoring zones that would otherwise require multiple fixed cameras. This dynamic repositioning capability provides universal coverage across different driving scenarios.

AI summary
A camera monitoring system includes a first camera configured to capture an image of an area including a predetermined area on the left side of a vehicle, a second camera configured to capture an image of an area including a predetermined area on the right side of the vehicle and a third camera configured to capture an image of an area including a predetermined area behind the vehicle. The camera monitoring system further includes a monitor configured to display a composite image including a first captured image captured by the first camera, a second captured image captured by the second camera and a third captured image captured by the third camera and an image processor configured to control a layout of the composite image, and change the layout according to at least either the moving body information or the environmental information.
