PROBLEM TO BE SOLVED: To accurately predict and revise the variation of the displaying color of a display following the variation of the color temperature of the display through simple matrix operation without rendering calibration information futile. SOLUTION: In a displaying color correcting section 20, a color value calculating section 23 calculates the color value under a designated light source from the premeasured spectral reflectances of the small number of color chips and the spectral distribution and color matching function of daylight at the color temperature set at the time of performing display calibration. A learning and processing section 22 decides the transformation matrix used for the correction of the displaying color by using the color value as learning data. Then a correcting and processing and section 25 converts the color value of an actual displaying color into the color value at the designated color temperature by using the obtained transformation matrix.
