1. A method, comprising:
receiving image brightness values from a plurality of image acquisition devices;
performing a weighted summation on the image brightness values of the plurality of image acquisition devices according to brightness weights preset by the plurality of image acquisition devices, to obtain a weighted sum value;
dividing the weighted sum value by a sum of the brightness weights preset by the plurality of image acquisition devices to determine an average brightness value of the plurality of image acquisition device;
determining a brightness difference value between the image brightness value of an image acquisition device of the plurality of image acquisition devices and the average brightness value as a brightness gain of the image acquisition device; and
configuring the image acquisition device with the brightness gain.
