Abstract:
1. A white balance adjusting method, comprising steps of: A. obtaining maximum spectral tristimulus values X B. converting the maximum spectral tristimulus values X C. converting the maximum color stimulus values L D. computing spectral stimulus values Y E. computing spectral stimulus values X F. determining spectral tristimulus values of the three colors red, green and blue of a white field of the respective gray levels for the panel to be tested according to the spectral tristimulus values X the step B particularly comprising converting the maximum spectral tristimulus values X where Xs, Ys, Zs are spectral tristimulus values of a CIE standard illuminant, L is the psychological lightness, a, b indicate the psychological chroma; the step E particularly comprising converting the hue H, the chroma C and the spectral stimulus values Y where a range of n is 1˜(max−1), Xs, Ys, Zs are the spectral tristimulus values of the CIE standard illuminant; the spectral tristimulus values of the CIE standard illuminant Xs=Ys=Zs=100.
