Abstract: Every digital cinema projector has different color characteristics, thus the color of each projector can be seen differently. To solve this problem, LUT (Look-up-Table) should be differently made for each target device during DI(Digital Intermediate) process. Also, 8-bit images, used in general display devices, should be expanded to 10-bit images which are generally used in digital cinema in Korea. However, ICC (International Color Consortium) profile of 10-bit 3D LUT is difficult to handle because of its large size and long transfer time. In this paper, we propose the method of expanding 8-bit 3D LUT for each target device using ICC profile with private tag to 10-bit 3D LUT by using geometric interpolation. By using (use of) the resulting 10-bit LUT, scene images are transformed to be suited for target digital cinema projector in the process between DI and mastering. The proposed method can reduce the time to transfer 10-bit full 3D LUT and give interoperability between devices based on ICC profiles as achieving color consistency between digital cinema projectors.
