Dynamic Indicator Color Adjustment for Vehicle Drive-Assisting Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visibility of indicators in vehicle drive assisting systems is compromised when the color of the captured image resembles the indicator's color, particularly at night or indoors due to lighting from head lamps, tail lights, or brake lights.
Innovation Solution
An image processing apparatus that dynamically changes the color of the drive assisting indicator based on the lighting conditions and the color of the captured image, using a color determinator to select complementary colors such as blue green or yellow when the image color is similar to red, to maintain visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the indicator is colored yellow or red for easy recognition, then the visibility of the indicator is improved under normal conditions, but the visibility deteriorates when the captured image color is similar to the indicator color due to lighting conditions
Solution Approach 1:
The indicator color is made dynamic rather than fixed. The color determinator dynamically determines the indicator color based on the detected background color from the captured image. The synthesizer then superimposes the indicator with dynamically adjusted color, ensuring visibility adapts to different lighting conditions such as nighttime or indoor environments where the background color may resemble traditional indicator colors.
Solution Approach 2:
The color parameter of the indicator is changed based on the detected background color. The color determinator analyzes the background color from the captured image and selects an appropriate indicator color that provides sufficient contrast. This parameter change ensures the indicator remains visible across varying lighting conditions while maintaining its alert function.
2Device complexity
If a fixed color indicator is used for simplicity, then the device complexity is reduced, but the reliability of indicator visibility under varying lighting conditions deteriorates
Solution Approach 1:
A feedback mechanism is implemented where the color determinator continuously monitors the background color from the captured image and adjusts the indicator color accordingly. The synthesizer receives this feedback and superimposes the indicator with the appropriately adjusted color. This feedback loop ensures the indicator maintains visibility reliability across different lighting conditions without requiring complex manual intervention.

AI summary
An image processing apparatus includes an I/F, a synthesizer, and a color determinator. The I/F obtains a captured image, which is generated by imaging a subject in the vicinity of a vehicle. The synthesizer superimposes an indicator on the captured image. The color determinator, when color of the captured image is similar to a first color, changes color of the indicator from the first color.
