Abstract

The invention discloses a light sensor calibration method and a device, a mobile terminal and a readable storage medium; the method comprises the following steps: obtaining light source data sensed by a light sensor from a standard light source in a preset time period; using preset filtering rules to filter the light source data so as to obtain target light source data; calibrating the light sensor according to the target light source data. Compared with the prior art, the method uses preset filtering rules to filter the light source data sensed by the light sensor from the standard light source, thus filtering abnormal data formed by manual operations or equipment reasons from the standard light source, and forming effective fool-proof effect; the method uses the filtered target light source data to calibrate the light sensor, thus effectively improving the calibration accuracy.

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...
