Vehicle Display Image Sharpness for Near-Far Object Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display devices, such as Head Up Displays, fail to effectively differentiate between important information close to and far from the vehicle, making it difficult for passengers to recognize critical information, especially when the vehicle is moving at high speeds.
Innovation Solution
The vehicle display device employs a system that dynamically adjusts the sharpness and visibility of displayed information based on distance from the vehicle, using a combination of cameras and processors to generate images that are more sharply visible for distant objects and less visible for nearby objects, reducing visual discomfort and improving recognition of important information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device shows all detected objects with equal clarity, then the complete information is provided, but the important distant information becomes difficult to recognize due to visual clutter from nearby objects
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics based on the spatial location of objects. Distant objects that require attention are displayed with high clarity and sharpness, while nearby objects are displayed with reduced clarity or blurred. This selective application of quality ensures that important information stands out without being obscured by less critical nearby objects, directly resolving the contradiction between providing complete information and avoiding visual clutter.
2Reliability
If the display device increases the visibility of distant objects, then important information recognition is improved, but the overall display balance is disrupted
Solution Approach 1:
The patent implements dynamics by continuously adjusting the display characteristics of different objects based on their distance, relevance, and the driver's needs. The system dynamically modifies the clarity, sharpness, and visibility of individual objects in real-time rather than using a static display approach. This dynamic adjustment allows the system to prioritize important distant information while maintaining overall display balance and avoiding disruption to the driver's visual experience.
3Loss of information
If the display device uses different representation methods for near and far objects, then important information becomes more recognizable, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying display parameters such as sharpness, clarity, brightness, and size based on the distance and importance of detected objects. The system adjusts these parameters dynamically to enhance the visibility of important distant objects while simplifying the representation of nearby objects. This approach improves information visibility without requiring fundamentally complex display mechanisms, as it leverages adjustable parameters within existing display technology.

AI summary
The objective of the present invention is to provide a vehicle display device with which it is possible for a passenger to be made aware more reliably of important information that is difficult to visually recognize. A vehicle display device 4 is provided with a display unit 10, an image generating unit 100 and a target object information acquiring unit 300. The display unit 10 displays a display image, the image generating unit 100 generates the display image, and the target object information acquiring unit 300 acquires target object information relating to a target object present at the periphery of a vehicle 1 and outputs the same to the image generating unit 100. The image generating unit 100 is characterized in that if the distance from the vehicle 1 to the target object exceeds a first reference value, the image generating unit 100 generates an information image of the target object in a sharply visible region, and if the distance from the vehicle 1 to the target object does not exceed the first reference value, the image generating unit 100 generates the information image of the target object in a blurred region, and in that the information image in the blurred region is generated to be less sharply visible than the information image in the sharply visible region.
