Abstract

An embodiment of the invention discloses a sensor calibration method, an electronic device and a computer readable storage medium and is applicable to the technical field of communication. The methodincludes: when a capacitive proximity sensor is registered by an application, detecting the screen state of a mobile terminal, and using the capacitance currently measured by the capacitive proximitysensor as the reference capacitance of the capacitive proximity sensor if the screen is on. By the sensor calibration method, the judging accuracy of the capacitive proximity sensor for judging a human face approaching the mobile terminal screen can be increased.

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...
