The invention discloses a white balance adjustment method, a computer readable storage medium and electronic equipment. The white balance adjusting method comprises the following steps: establishing a color coordinate system taking R/G and B/G as axes; taking color coordinates of images of a white target object or a gray target object shot under light sources with different color temperatures as white points and marking the white points in the color coordinate system; fitting a color temperature curve based on the white points; a colorless area is set in the color coordinate system, the colorless area covers part or all of the color temperature curve, and the number of white points in the colorless area is larger than the number of white points outside the colorless area; dividing an original image into statistical units which are not overlapped with each other, and establishing a color coordinate point corresponding to each statistical unit in the color coordinate system; setting a weight value for the color
