Claim 3:
4. The device according to claim 1, wherein the interpolation value of the interpolation point is calculated based on following formula,

D=[DAL+(DD−DC)r+(DC−DA)g+(DB−DA)b]/L, wherein, D represents the interpolation value of the interpolation point, DA, DB, DC and DD are mapping values of four vertices A, B, C and D of the tetrahedron surrounding the interpolation point respectively, (r, g, b) represents coordinates of the interpolation point in the sampling space, L represents the side length of a cube formed of nearby eight sampling points surrounding the interpolation point in the sampling space, side CD is parallel to X-axis, side CA is parallel to Y-axis, and side BA is parallel to Z-axis.
