A color image processing apparatus for reproduces color data of a subject at higher accuracy by estimating the spectral reflectance of the subject from the color chip basis function vn (lambd) which can expand the spectral reflectances of all color chips of the reference chart and the expansion coefficients B of the color chips. The color image processing aparatus uses an image processing device to which a subject shooting signal Q shot by the color image input device and a reference chart shooting signal G taken from a plurality of color chips each having a spectral reflectance is known.
