AI Technical Summary

Technical Problem

In existing technologies, the light sensor is installed in a fixed position, which leads to blind spots and misadjustment, making it impossible to perceive the spectral information or hue of the environment, thus affecting the screen display effect and the driver's visual experience.

Method used

By using cameras on the vehicle to acquire image signals of the external environment and the cockpit, and by calculating the brightness and chromaticity adjustment values ​​of the target instrument screen, combined with image data from four surround-view cameras and the cockpit interior camera, the screen brightness and chromaticity can be automatically adjusted.

Benefits of technology

It achieves seamless light and color perception, smoother and more accurate screen brightness adjustment, improves driver visual comfort and screen display naturalness, and enhances icon recognizability and work efficiency.

Abstract

This invention discloses a method and system for automatically adjusting the brightness and hue of a vehicle screen. The method includes: acquiring image signals of the external environment and the cockpit environment from cameras on the vehicle; calculating the target instrument panel screen brightness based on the image signals from the cameras; obtaining the three primary color ratios from the image signals of each camera; fusing the three primary color ratios of all cameras to calculate the target three primary color ratio; obtaining the target chromaticity adjustment value based on the target three primary color ratio; and adjusting the instrument panel screen using the target brightness and the target chromaticity adjustment value. This solution utilizes the vehicle's built-in cameras to comprehensively judge the ambient light outside the vehicle and the local lighting inside the vehicle, providing a truly comfortable and eye-protecting display effect, and ensuring that the brightness and hue of the instrument panel screen are synchronized and accurately adjusted.
