Map Image Processing Highlighting Focus Colors for Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing technologies, such as those used in car navigation, fail to quickly highlight important information, leading to driver distraction due to the lack of a focal point in video and image presentations.
Innovation Solution
A method and device for processing map images by highlighting a focus color, increasing its saturation and/or brightness, to draw attention to critical information, thereby facilitating quicker information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video or image presentation is used to present information, then information presentation becomes more intuitive and convenient, but it becomes difficult to quickly obtain important information due to lack of focal point
Solution Approach 1:
The patent applies color changes by adjusting the saturation of specific color ranges in the map image. It identifies focus colors (such as blue for POIs, green for routes, red for road conditions) and increases their saturation to make them stand out visually, while reducing the saturation of non-focus colors. This creates a focal point effect that helps users quickly locate important information without sacrificing the intuitive visual presentation of the map.
Solution Approach 2:
The patent employs parameter changes by modifying the saturation parameter of pixels based on their color characteristics. It converts images to HSV color space, identifies pixels within specific hue ranges corresponding to focus colors, and applies different saturation adjustment factors to these pixels versus others. This selective parameter modification enables quick identification of important information while maintaining overall image quality.
2Loss of information
If driver focuses on the screen to obtain important information from navigation, then important information can be obtained, but driver distraction increases
Solution Approach 1:
By enhancing the saturation of focus colors that represent critical navigation information (route directions, POIs, warnings), the patent makes important information visually prominent and immediately recognizable. This allows drivers to quickly grasp essential navigation cues with minimal screen attention, thereby reducing distraction while ensuring important information is effectively communicated.
3Loss of information
If saturation of focus color is increased to highlight important information, then important information becomes more prominent, but color distortion may occur
Solution Approach 1:
The patent applies local quality by selectively adjusting the saturation of only those pixels that fall within specific hue ranges corresponding to focus colors. Non-focus pixels retain their original saturation values. This localized approach ensures that important information becomes prominent while other elements of the map maintain their natural color appearance, preventing overall color distortion and preserving the authenticity of the map visualization.
