The embodiment of the invention discloses a proximity sensor calibration method and device, a mobile terminal and a readable storage medium. The method comprises the steps that the history calibration compensation value of a proximity sensor is acquired; the current proximity value of the proximity sensor is acquired; the error between the proximity value and a preset reference proximity value is calculated; and the proximity sensor is calibrated according to the error and the history calibration compensation value. Compared with the prior art, the method provided by the invention has the advantages that the history calibration compensation value and the error between the current proximity value of the proximity sensor and the preset reference proximity value are used for calibration; the time taken for the calibration process is effectively shortened; and the probability of calibration failure is reduced.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a calibration method and device for a proximity sensor, a mobile terminal and a readable storage medium. Background technique [0002] A proximity sensor is a device capable of sensing the proximity of an object, and is widely used in mobile terminals to detect whether an object is approaching the mobile terminal. [0003] In real life, a layer of oil stains or scratches is often attached to the surface of mobile terminals due to the sliding of fingers. In addition, most users are used to sticking a layer of film on the surface of mobile terminals, so the detection results of proximity sensors in mobile terminals will inevitably be different. It is affected to a certain extent, so that the mobile terminal is prone to misjudgment. [0004] At present, in order to solve the problem that the detection results of the proximity sensor are affected by oil and film, most mobil...
