Abstract

The embodiment of the invention discloses an image brightness adjusting method. The method comprises: an image acquisition instruction is received, responding to the image acquisition instruction is carried out, and then an image acquisition device collects a target image; a current brightness value of the target image is obtained and whether the current brightness value of the target image meetsa preset condition is determined; if so, a target brightness value is determined based on the current brightness value of the target image, wherein the target brightness value is smaller than the current brightness value; and the current brightness value of the target image is adjusted to be the target brightness value. Meanwhile, the embodiment of the invention also discloses a terminal and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of electronic devices, and in particular, to an image brightness adjustment method, a terminal and a computer-readable storage medium. Background technique [0002] With the development of smart terminals, the shooting function has gradually become an indispensable function of the smart terminals, and more and more users prefer to use the cameras of the smart terminals to shoot and record pictures worth cherishing in life. When the user uses the smart terminal to shoot, when the shooting environment is dark, the flash needs to be turned on to increase the exposure. However, when the exposure brightness of the shooting is adjusted by the flash, overexposure is very likely to occur. In this way, the brightness of the captured image is too high, and the image becomes white. [0003] At present, for overexposed images, the user needs to manually adjust with the help of retouching software. Specifically, the user ...
