AI Technical Summary
Existing technologies make it difficult to accurately detect user actions when illumination is applied near the electrostatic capacitive sensor, potentially leading to false detections and malfunctions.
By placing an illumination device near the electrostatic capacitance sensor, the baseline is dynamically adjusted using a baseline setting unit and an illumination control unit to adapt to temperature changes caused by the illumination device being turned on. Combined with a RAW detection unit and an operation detection unit, accurate detection of user operations is achieved.
When the lighting device is turned on, it can accurately detect the user's operation, avoid false detection, and improve the accuracy and reliability of operation detection.
