Abstract

The embodiment of the present invention discloses an image brightness adjustment method, a terminal, and a computer-readable storage medium, wherein the method includes: determining the first brightness average value and the second brightness average value of the collected image, wherein the The first average brightness is the average brightness of the entire image, and the second average brightness is the average brightness of the face area in the image; determined according to the first average brightness and the second average brightness A third brightness average value of the image; determining a brightness adjustment value of the image according to the third brightness average value; adjusting the brightness of the entire image according to the brightness adjustment value.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to an image brightness adjustment method, terminal and computer-readable storage medium. Background technique [0002] With the rapid development of communication technology, terminals are becoming more and more intelligent. For example, smart phones or tablet computers have more and more functions. The mobile communication terminals are no longer simply used to meet people’s mutual connections. , It has become a very important mobile personal entertainment terminal in people's daily life. [0003] At present, the camera function has become an indispensable function of smart terminals, and people can record wonderful moments anytime and anywhere. When shooting, in a backlit environment, the brightness of the human face will be much darker than the background. Conversely, if the light source directly shines on the face, the brightness of the face will be much brighter t...
