Abstract

The invention provides a screen brightness adjusting method and a mobile terminal, and relates to the technical field of mobile terminals. The method includes: obtaining an ambient brightness value, obtaining the number of bright pixels in an image displayed by the mobile terminal when the ambient brightness value is less than a brightness threshold, and adjusting the brightness of a screen of themobile terminal according to a scale parameter corresponding to the bright pixels; determining whether the mobile terminal needs to adjust the brightness of the screen through the obtained ambient brightness value, obtaining the number of the brightness pixels in the currently displayed image when the ambient brightness value is less than the brightness threshold, and obtaining the scale parameter corresponding to the bright pixels with the combination of the number of all the pixels in the image; and finally adjusting the brightness of the screen according to the scale parameter. The brightness of the screen can be accurately adjusted, clear face images can be obtained after the mobile terminal adjusts the brightness of the screen, and the accuracy and the flexibility for adjusting the brightness of the screen are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a screen brightness adjustment method and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals, mobile terminals can not only capture objects or landscape images through the rear camera, but also obtain user face images through the front camera to meet the different needs of users, such as Selfie, mobile terminal unlocking and quick access. Pay etc. [0003] In the related art, when the mobile terminal is in an environment with a low degree of light and darkness, that is, when the mobile terminal is in a relatively dark environment, if the mobile terminal needs to collect the user's face image, the screen of the mobile terminal can be adjusted. Brightness, so as to increase the brightness of the current environment, and then obtain a clear face image. [0004] However, the existing methods for ad...
