Abstract: Correct colour reproduction is an important factor in digital cinema. To do that, this paper proposes methods of colour correction by means of look-up-table (LUT) interpolations. Reference colour patches are taken by movie camera like taking a clapperboard shot which is generally used for sound synchronisation. Once the shooting is completed, device characterisation is performed to generate the 3D LUT for correct colour reproduction. By using the LUTs, any colours taken from camera under any illumination conditions can be converted to the colours under any preferred illumination conditions by means of a tri-linear interpolation. Finally, the real scenes can be colour changed to any illumination conditions without visual discrepancies. This paper also presents another 3D LUT type in which input RGB colours can be directly converted to output RGB colours without device characterisation. This LUT can be easily adapted to the stereoscopic cameras so that pairs of stereo images may match each other
