Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle rear-view systems, including mirrors and cameras, fail to provide clear visibility of rearward obstacles and parking spaces, especially at night and in blind spots, leading to potential accidents and inconvenience.
Innovation Solution
A camera apparatus equipped with an image sensor, brightness measurer, and controller that adjusts image quality based on brightness, combines parking information with the image, and detects moving objects or obstacles, allowing for enhanced visibility and safe parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a rear-view camera device is equipped to view behind the vehicle, then visibility of rearward obstacles is improved, but image quality in low brightness conditions deteriorates
Solution Approach 1:
The patent applies dynamics by making the image processing parameters adjustable based on detected brightness levels. The controller dynamically changes gamma correction values, sharpness, and contrast settings according to the measured brightness, enabling the system to adapt to varying lighting conditions and maintain reliable visibility both during day and night
Solution Approach 2:
The patent implements parameter changes by modifying image processing parameters (gamma, sharpness, contrast) based on brightness measurements. The controller adjusts these parameters to optimize image quality for different lighting conditions, thereby resolving the contradiction between maintaining good image quality and ensuring reliable visibility in low brightness environments
2Loss of information
If the driver turns head to check blind spots, then detection of side obstacles is improved, but driving safety and convenience deteriorate
Solution Approach 1:
The patent applies universality by creating a multi-functional rear-view system that not only captures images but also detects moving objects, measures brightness, processes images with adjustable parameters, and provides comprehensive blind spot monitoring. This integrated system eliminates the need for separate actions to check different areas, maintaining driving safety while providing complete information
3Reliability
If parking space width detection is added to the camera system, then parking safety is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a camera system that performs multiple functions: image capture, brightness measurement, moving object detection, image processing with adjustable parameters, and parking space width detection. By integrating these functions into a single multi-functional system rather than separate devices, the patent improves parking safety while minimizing the increase in overall device complexity
