Abstract

An embodiment of the present application provides a proximity sensor calibration method, an electronic device, and a computer-readable storage medium, which relate to the technical field of mobile terminals, wherein the method includes: when the infrared light of the proximity sensor is turned off, acquiring multiple continuous proximity sensor values, according Calculate the calibration reference value of the proximity sensor for the plurality of continuous proximity sensor values, and if the calibration reference value is greater than the first value, confirm whether the calibration reference value and the plurality of continuous proximity sensor values ​​meet the calibration trigger condition, if If the calibration trigger condition is met, the proximity threshold of the proximity sensor is increased by a second value. The application can improve the accuracy of proximity sensor sensing.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular to a method for calibrating a proximity sensor, an electronic device, and a computer-readable storage medium. Background technique [0002] The proximity sensor (PS, Proximity sensor) judges the distance by emitting and receiving infrared light, and judges the approach and distance of the obstruction according to the change of the infrared energy reflected back by the obstruction. However, it is easily affected by sunlight and infrared interference from various indoor light sources, causing the value of the proximity sensor to jump, and there is a risk of misjudgment. [0003] In the prior art, the environmental infrared filtering mechanism is generally set on the mobile phone chip, but this filtering mechanism can only filter out the stable infrared interference in the environment. If the infrared light in the environment is changing, the infrared filtering ...
