AI Technical Summary

Technical Problem

In existing technologies, the brightness adjustment of displays lacks adaptation to the visual characteristics of the human eye. The adjustment process is prone to causing visual discomfort, and the predictability of light intensity changes is insufficient, making it impossible to accurately correct the hardware characteristics of display devices.

Method used

By analyzing the trend of ambient light intensity changes to determine the directional characteristics of light brightness, smooth curve parameters adapted to human visual adaptation are generated. Combined with the visual adaptation model and light prediction, a brightness transition sequence is generated, a primary adjustment and backup path are constructed, and brightness is gradually adjusted to achieve closed-loop precise control.

Benefits of technology

It improves visual comfort, reduces visual fatigue, ensures that brightness adjustment matches the human eye's adaptation rules, achieves adaptive response to various light intensity changes, and guarantees the continuity and stability of brightness adjustment.

Abstract

The invention relates to the technical field of intelligent control, and discloses a display screen brightness adaptive adjustment method and system, and the method comprises the steps: obtaining environment light intensity data, analyzing a change trend, and determining a light brightness directivity feature as an adaptive speed adjustment basis; adaptive speed adjustment generates smooth curve parameters adaptive to human eye characteristics according to an input visual adaptation model, a brightness transition sequence is generated through discretization sampling, and the brightness transition sequence is converted into an adjustment instruction set; obtaining a target reference value from the adjustment instruction set, and calculating the deviation between the actual brightness and the target reference value through a feedback mechanism to obtain a corrected brightness value; real-time light intensity and historical data are fused to construct a time sequence set, a light expected sequence is predicted, main and standby adjusting paths are generated, and self-adaptive switching is carried out according to the light intensity deviation degree; a current adjusting instruction is extracted and transmitted to the display driving module, and brightness gradient adjustment and a visual comfort state are achieved. The method can realize accurate adaptation of human eye characteristics and display device hardware.
