Abstract

The embodiment of the present invention discloses a sensor calibration method, which is applied in the field of communication technology, including: when the capacitive proximity sensor is registered by the application, detecting the screen state of the mobile terminal, and if the screen state is the bright screen state, setting the capacitive proximity sensor to The capacitance value currently measured by the sensor is used as the reference capacitance value of the capacitive proximity sensor. The embodiment of the invention also discloses an electronic device and a computer-readable storage medium, which can improve the accuracy rate of a capacitive proximity sensor in judging that a human face approaches a screen of a mobile terminal.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a sensor calibration method, an electronic device and a computer-readable storage medium. Background technique [0002] With the popularity of full screens, there is almost no space for proximity infrared sensors on the front of mobile phones, so capacitive proximity sensors such as SAR (Specific Absorption Rate) sensors will be used to replace proximity infrared sensors. Capacitive proximity sensors can be placed near the antenna area of ​​a mobile phone to detect whether a human face is approaching by sensing capacitance. [0003] However, the capacitive proximity sensor may detect errors. When there is liquid on the mobile phone screen to generate capacitance, the capacitive proximity sensor will mistakenly recognize the face proximity state due to the detected capacitance value, resulting in abnormal recognition and affecting the normal function of the mobil...
