Screen Brightness Adjustment via Camera AEC Illumination

The patent introduces the camera's AEC system as an intermediary to measure illumination value independently from the optical sensor. This intermediary measurement system allows the screen brightness adjustment to be decoupled from the ambient light detection, enabling the screen to be brightened based on camera illumination needs without affecting the camera's image capture capability in low-light conditions

The patent implements dynamic screen brightness adjustment by continuously monitoring the camera's working state and AEC illumination value. When the camera is active, the screen brightness dynamically changes based on the AEC-measured illumination, allowing real-time adaptation that prioritizes image detail visibility while maintaining screen adaptability to ambient light conditions

The patent implements conditional dynamic brightness adjustment where the screen brightness behavior changes based on camera state. When the camera is inactive, the screen follows energy-saving dimming in dark ambient light. When the camera is active, the screen dynamically brightens based on AEC illumination measurement, ensuring image detail clarity is prioritized during camera use while maintaining energy efficiency during normal operation

The patent applies preliminary anti-action by proactively brightening the screen before the user needs to view image details. The system monitors camera activation and preemptively adjusts screen brightness based on AEC illumination values, preventing the problem of insufficient visibility from occurring in the first place during camera operations
