A white balance compensation method enabling highly accurate image white balance compensation is conducted by a white balance compensation system. Digital image data acquired by a data acquisition unit is sent to a mean value computing unit that effects a computation on color signals B, G and R which are n-th powers of incident light intensity to calculate mean values Bm, Gm and Rm thereof as:where p is a coefficient of the power n falling in the range of 0.5<=p<=1.5, preferably in the range of 1.0<=p<=1.5. The mean values Bm, Gm and Rm are sent to a conversion means that converts the color signals so as to make two of the mean values other than a selected one coincide with the selected mean value, thereby enabling reproduction of a white-balance compensated image free of color failure.
