Abstract

Embodiments of the present invention disclose a method for adjusting image brightness, a terminal, and a computer-readable storage medium. The method includes: determining a first average brightness value and a second average brightness value of a collected image, wherein the first brightness average value is a brightness average value of the entire image, and the second brightness average value is a brightness average value of a face area in the image; and according to the first brightness average value and the second brightness average value, determining a third brightness average value of the image; determining a brightness adjustment value of the image according to the third brightness average value; and 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, in particular to an image brightness adjustment method, a terminal and a 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. , 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 face will be much darker than the background. Conversely, if the light source directly shines on the human face, the brightness of the human face will be much brighter than the background. And when the brightness of the face is obviously brighter or darker...
