Disclosed is an image processing apparatus for converting input image data based on n dimensional color space to output image data based on m dimensional color space, comprising: a storing section to store a color conversion value in the m dimensional color space determined for every lattice point obtained by dividing the n dimensional color space as lattice point data; and a color converting section to determine an interpolating operation point in the n dimensional color space based on the input image data, to perform an n dimensional Bi-cubic interpolating operation by using the lattice point data of a primary neighborhood lattice point and the lattice point data of a secondary neighborhood lattice point of the interpolating operation point out of the stored lattice point data, and to calculate a color conversion value of the interpolating operation point in the m dimensional color space.
