1. A method for adjusting screen brightness of a terminal, comprising:
- obtaining ambient light brightness value, and setting a first screen display brightness value corresponding to the ambient light brightness value as a screen display brightness value;
monitoring a working state of a camera of the terminal, obtaining illumination value of the camera, and looking up a second screen display brightness value according to the illumination value of the camera;
comparing the first screen display brightness value with the second screen display brightness value, setting the second screen display brightness value as the screen display brightness value when the second screen display brightness value is greater than the first screen display brightness value; and
setting the first screen display brightness value as the screen display brightness value when the camera is off by the terminal;
wherein during the step for monitoring the working state of the camera of the terminal, obtaining the illumination value of the camera, and looking up the second screen display brightness value according to the illumination value of the camera, the step comprises;
monitoring the working state of the camera of the terminal, obtaining, by an Automatic Exposure Control (AEC) system, the illumination value of the camera; and
looking up the second screen display brightness value according to the illumination value of the camera.

Abstract
A method, a system, and a terminal for adjusting screen brightness of the terminal includes the steps of obtaining a first screen display brightness value corresponding to ambient light brightness value, and obtaining illumination value of a camera and looking up a second screen display brightness value. When the second screen display brightness value is greater than the first screen display brightness value, the second screen display brightness value is set as the screen display brightness value. Namely, the display brightness is controlled by an Automatic Exposure Control (AEC) system, which increases displaying detail of image on the display.
