- Abstract
- A new method of color space conversion for the laser film recorder is proposed. The input image file (10 bits or more, RGB) is converted by a three-dimensional lookup table (3-D LUT), then fed to the film recorder as data from 10-bit RGB. Using this method, the image on print films is colorimetrically improved and matched to the image on a CRT monitor. This paper reviews a color transformation by conventional film recording that uses only one-dimensional LUT. A 3-D LUT is built based on a gamut mapping algorithm to compensate for the difference of the color gamut between CRT monitors and print films, employing a new soft-clipping method. Three gamut compression (clipping) methods are also evaluated. The calculation on the 3-D LUT is based on CIE LAB color coordinates evaluated by several observers. A guideline for quality control of color management in film laboratories is also discussed. This new system has been successfully applied to the production of feature animation footage.
