AI Technical Summary

Technical Problem

Conventional head-up displays do not adequately consider visibility when occupants are wearing sunglasses, leading to dim display content and potential overlooking of important information, especially in bright environments, and require manual brightness adjustments which are impractical and unsafe.

Method used

A head-up display illumination control system that detects whether an occupant is wearing sunglasses using a camera and image analysis, and automatically adjusts the display brightness to compensate for light attenuation, ensuring optimal visibility by increasing the illumination level when sunglasses are detected.

Benefits of technology

The system maintains consistent visibility by automatically adjusting brightness based on sunglasses wear, reducing operational burden and enhancing safety by preventing the need for manual adjustments and ensuring clear display content.
