DYNAMIC DISPLAY BRIGHTNESS CONTROL USING FACIAL DETECTION VIA ALWAYS-ON CAMERA TO REDUCE SMARTPHONE POWER CONSUMPTION

原文（中国語）

Dynamically controlling the display brightness of a smartphone to reduce power consumption using facial detection via an always-on camera. The smartphone is equipped with a dedicated low-power always-on (AON) camera system that performs facial detection to determine whether the user is actively looking at the screen. When the user is not looking at the screen, the display brightness is automatically lowered to a preset level or by a percentage to reduce display power consumption. When the user's face is subsequently detected, the brightness is increased based on ambient light sensor readings. The AON camera system enables power optimization while also supporting instant face unlock, hands-free convenience features, and enhanced security. By dynamically adjusting the display brightness based on user engagement, battery life is significantly extended without compromising the user experience.
