Abstract: A white balance processing method and an electronic device are provided, related to the field of image processing. The white balance processing method includes: displaying a first interface, where the first interface includes a first control; detecting a first operation on the first control; obtaining a first image in response to the first operation, where the first image refers to an image of a first color space captured by a multispectral color filter array sensor; performing decomposition processing and demosaicing processing on the first image to obtain a second image and a third image, where the second image is an image in a first color mode and the third image is an image in a second color mode; obtaining a color correction matrix according to the second image and the third image, where the color correction matrix is used for representing a pixel change amount of transforming the second image into the third image; inputting the color correction matrix into a white balance model to obtain a white balance parameter; and performing image processing on the first image according to the white balance parameter to obtain a fourth image. Based on the technical solutions according to this application, the color accuracy in an image can be improved.
