HUD Pixel Brightness Adjustment for Driver Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Head-Up Display (HUD) systems distract drivers and cause visual fatigue due to uniform brightness across all pixels, leading to potential traffic accidents.
Innovation Solution
A method and apparatus that adjust the display brightness of each pixel in a HUD image based on its distance from a reference position related to the driver's focal point, weakening brightness in areas not focused on to reduce distraction and fatigue.

Engineering Contradiction Analysis
1Object-affected harmful factors
If uniform brightness is used across all pixels in HUD image, then manufacturing and display simplicity is maintained, but driver distraction and visual fatigue increase
Solution Approach 1:
The patent applies local quality by adjusting brightness differently across different regions of the HUD image. Specifically, pixels closer to the focal position (where the driver's eye focuses) maintain higher brightness, while pixels farther away have reduced brightness. This creates a gradient brightness distribution that matches the driver's natural focal attention pattern, reducing distraction from peripheral areas while maintaining visibility of critical information at the focal point.
2Loss of information
If brightness is weakened in non-focused areas, then driver focus on relevant information is improved, but overall image visibility may be compromised
Solution Approach 1:
The patent implements dynamics by making the brightness adjustment adaptive rather than static. The system dynamically calculates the focal position of the driver's eye and adjusts the brightness distribution accordingly. As the driver's focal point moves or changes, the brightness gradient automatically recalibrates to maintain optimal visibility. This dynamic adaptation ensures that critical information remains visible while minimizing distraction, without sacrificing overall image visibility.

AI summary
A display adjustment method and apparatus, a system, and a storage medium. The method includes: obtaining a reference position from an image displayed by a head-up display HUD system, where the reference position is related to a focal position, on the image displayed by the HUD system, of an eye of a user; obtaining a brightness weakening coefficient of each pixel based on a distance between each pixel in the image and the reference position; adjusting display brightness of each pixel in the image based on the brightness weakening coefficient of each pixel; and displaying an adjusted image based on the display brightness of each pixel in the adjusted image.
