Proximity sensor calibration methods, electronic devices and computer readable memory medium

Abstract

The embodiments of the invention provide proximity sensor calibration methods, electronic devices and a computer readable memory medium and relates to the technical field of a mobile terminal. A method comprises the steps of obtaining a plurality of continuous proximity sensor values when an infrared lamp of a proximity sensor is turned off; computing a calibration reference value of the proximitysensor according to the plurality of continuous proximity sensor values; confirming whether the calibration reference value and the plurality of continuous proximity sensor values satisfy a calibration triggering condition or not if the calibration reference value is greater than a first value; and increasing a proximity threshold of the proximity sensor by a second value if the calibration triggering condition is satisfied. According to the methods, the electronic devices and the computer readable memory medium, sensing accuracy of the proximity sensor can be improved.

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 ...
