Vehicle Camera Display Harmonization for Faster Object Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles with multiple cameras, the uncoordinated display of camera images from different assistance systems leads to inconvenient and potentially unsafe situations due to varying image and display properties, requiring users to adjust their viewing and often resulting in delayed object recognition.
Innovation Solution
A method for harmonizing camera image data from different assistance systems by standardizing image and display properties using a central harmonization device or closed-loop/open-loop control systems, ensuring uniform representation across multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different assistance systems with multiple cameras are used to capture vehicle surroundings, then the coverage and functionality of the system is improved, but the consistency and uniformity of image representation deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting image processing parameters such as brightness, contrast, color balance, and sharpness for each camera image. The control unit modifies these parameters based on camera-specific characteristics and ambient lighting conditions to achieve uniform appearance across all images while maintaining their individual functional advantages.
Solution Approach 2:
The system implements feedback mechanisms where the control unit continuously monitors image quality metrics and ambient lighting conditions, then adjusts processing parameters accordingly. This closed-loop approach ensures that images from different cameras with varying characteristics are harmonized to present a consistent visual representation to the user.
2Reliability
If camera images from different assistance systems are displayed with their original properties, then the authenticity of each camera's output is preserved, but the user's recognition speed and accuracy deteriorates
Solution Approach 1:
The control unit modifies display parameters such as brightness, contrast, and color balance to create a unified visual appearance across all camera images. This harmonization allows users to quickly recognize objects and spatial relationships without being distracted by inconsistent image properties, thereby reducing recognition time while maintaining the authentic spatial information from each camera.
3Ease of operation
If images are processed to achieve uniform appearance across multiple cameras, then user convenience and safety are improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent segments the image processing task by applying specific processing algorithms to individual cameras based on their characteristics. Each camera image is processed independently with tailored parameters, then the results are combined for display. This segmented approach manages computational complexity while achieving the desired uniform appearance and user convenience.

AI summary
A method for making vehicle surroundings visible in a motor vehicle for a vehicle occupant, includes a step of recording camera image data, and performing harmonization. In the step of recording, image data of the vehicle surroundings is recorded with multiple different assistance systems of the motor vehicle which each comprise at least one camera. The Harmonization is performed in terms of specified image and/or display properties for homogeneous display of the camera image data with at least one display device of the motor vehicle. Camera image data, required for display with the at least one display device, of the different assistance systems are homogeneously displayed, and correspondingly harmonized.
