Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle camera systems require multiple cameras with differently designed fields of view for various applications, leading to increased complexity and cost due to the need for distinct camera installations for each application, and the distortion issues in wide-angle views affect image perception.
Innovation Solution
A vehicle camera system with front, left, and rear cameras that can dynamically adjust their field of view based on operating modes (around view, driving, black box, and mirror modes) using variable moving or liquid lens technology, controlled by a processor to optimize image capture and reduce distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras with differently designed fields of view are installed for various applications, then the system can meet diverse application requirements, but the device complexity and installation cost increase
Solution Approach 1:
The patent applies universality by designing a single camera system that can perform multiple functions through variable field of view. The camera uses a movable lens or liquid lens mechanism to dynamically adjust its field of view angle, allowing one camera to replace multiple fixed-field-of-view cameras for different applications such as around view monitoring, driving recording, and mirror functions
Solution Approach 2:
The patent applies dynamics by implementing a variable field of view capability through movable lens or liquid lens technology. The lens can dynamically change its focal length or position in response to control signals, enabling the camera to adapt its field of view angle based on different operating modes and driving conditions
2Area of stationary object
If a fixed wide-angle field of view is used for around view mode, then the coverage area is maximized, but image distortion increases
Solution Approach 1:
The patent applies dynamics by enabling the camera to dynamically adjust its field of view angle based on operating conditions. During around view mode with low driving speed, the camera uses a wide field of view for maximum coverage. When driving speed exceeds a threshold, the camera automatically switches to a narrow field of view to minimize distortion, providing optimal image quality for different scenarios
Solution Approach 2:
The patent applies parameter changes by modifying the field of view angle parameter based on driving speed and operating mode. The control device adjusts the lens position or focal length to change the field of view from wide-angle to narrow-angle, optimizing the balance between coverage area and image quality for different driving conditions
