Abstract

The invention discloses a calibration method, device, mobile terminal and readable storage medium of an optical sensor. The method includes: acquiring light source data sensed by the optical sensor from a standard light source within a preset time period, and using preset filtering rules to The light source data is filtered to obtain target light source data, and the light sensor is calibrated according to the target light source data. Compared with the existing technology, the preset filtering rules are used to filter the light source data sensed by the light sensor from the standard light source, so that the abnormal data in the standard light source caused by human operation or equipment can be filtered out, forming an effective It is fool-proof, and uses the filtered target light source data to calibrate the light sensor, which can effectively improve the accuracy of calibration.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for calibrating an optical sensor, a mobile terminal and a readable storage medium. Background technique [0002] At present, the display devices of mobile terminals such as smartphones and tablet computers need to use light sensors to detect the intensity of ambient light, so that the intensity of ambient light can be used to intelligently adjust the brightness of the backlight of the display device in conjunction with the display brightness of the display device of the mobile terminal. The purpose of intelligently adjusting the brightness of the backlight can also improve user experience and save energy consumption. Therefore, as an input quantity, the accuracy of ambient light is very important. [0003] In the prior art, a standard light source is used for the calibration of the light sensor of the mobile terminal, and the accuracy of the...
