Abstract
The application provides a white balance adjustment method, apparatus, camera, and medium. This method includes: obtaining a current image taken by the camera; determining a brightness value of the image and the acquisition parameter values with which the image is captured by the camera, in which the acquisition parameter values includes the exposure time, the exposure gain and the aperture value with which the image is captured by the camera; determining the first white balance gain, according to brightness value, exposure time, exposure gain and aperture value; calculating a second white balance gain with which the image is captured by the camera, according to the three-primary-color values of the pixel points of the image; adjusting the white balance gain of the camera according to the first white balance gain and the second white balance gain. The white balance gain determined by the embodiment of this application may better compensate for the color difference of the image taken by the camera.
