Problems solved by technology

Take a mobile phone as an example. When a user uses a mobile phone to talk, the screen of the mobile phone is usually attached to the ear, which may stain the screen with a layer of oil. If the oil stains near the light sensor, it will affect the environment detected by the light sensor. Light intensity, resulting in inaccurate detected ambient light intensity

Abstract

The invention belongs to the technical field of communications, and provides a method for compensating for ambient light intensity and a mobile terminal. The method comprises the following steps: when a proximity sensor is in a remote state, acquiring N groups of data of the proximity sensor; acquiring first proximity sensor data according to the N groups of data of the proximity sensor; if the first proximity sensor data are greater than a preset standard value of the proximity sensor data, calculating an increase proportion of the proximity sensor data according to the standard value and the first proximity sensor data; acquiring a reduction proportion of ambient light intensity corresponding to the increase proportion of the proximity sensor data according to the increase proportion of the proximity sensor data; acquiring current ambient light intensity of the mobile terminal; and correcting the current ambient light intensity according to the reduction proportion of the ambient light intensity in order to compensate for the current ambient light intensity. Through adoption of the method and the mobile terminal, the ambient light intensity detection accuracy can be increased, and backlight of a mobile terminal screen can be adjusted more accurately.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for compensating ambient light intensity and a mobile terminal. Background technique [0002] At present, the screen side of the mobile terminal is provided with a light sensor for detecting the ambient light intensity of the environment where the mobile terminal is located. Different ambient light intensities may correspond to different backlight levels of the mobile terminal screen. Take a mobile phone as an example. When a user uses a mobile phone to talk, the screen of the mobile phone is usually attached to the ear, which may stain the screen with a layer of oil. If the oil stains near the light sensor, it will affect the environment detected by the light sensor. Light intensity, resulting in inaccurate detected ambient light intensity. [0003] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. ...
