摘要

The present application provides a white balance processing method and device for an image. The method comprises: dividing a plurality of color features corresponding to a first image into near color features and far color features, wherein a distance between the near color feature in a color plane and one or more light source calibration points is less than or equal to a distance threshold value separately corresponding to one or more light source calibration points, and a distance between the far color features in the color plane and each light source calibration point of at least one light source calibration point is respectively greater than a distance threshold value corresponding to each light source calibration point; determining a first standard light source according to the near color features, and determining a second standard light source according to the far color features; determining a white balance gain according to the color feature of the first standard light source and the color feature of the second standard light source; and performing white balance processing on the first image according to the white balance gain so as to obtain a second image. According to the technical solutions, a color of an object in the image obtained by white balance processing can be close to a real color of the object in the image.
