The present invention relates to a white balance adjustment method, comprising: acquiring maximum and minimum spectral tristimulus values, and spectral tristimulus values of grayscales of red, green and blue; calculating an intermediate spectral tristimulus value of Y; fixing a chromatic value and setting a function in which the spectral tristimulus value changes with the grayscales; establishing a polynomial relation between the spectral tristimulus values of the tree colors of the white field and the spectral tristimulus values of the color field; and obtaining the number of grayscales of the three colors in the white field through approximation. In the present invention, the brightness exponentially changes with the grayscales, and the white field is adjusted by fixing the chroma of the white color spots. |
