Abstract:
A color management system for converting computer graphics images to film images, comprising;determining a first RGB to XYZ mapping applicable to the monitor, said first RGB to XYZ mapping using color spaces incorporating chromaticity and intensity data for each color component; recording a plurality of film images onto film using a film recorder driven with specified RGB values; outputting the plurality of film images with a projection system as a plurality of projected images; recording a plurality of light samples from the plurality of projected images; determining a second RGB to XYZ mapping applicable to the film recorder in response to the plurality of light samples and the specified RGB values, the second RGB to XYZ mapping using color spaces incorporating chromaticity and intensity data for each color component; and determining an RGB to RGB mapping, incorporating chromaticity and intensity data for each color component, for operating on the image colors displayed on the monitor to create accurate color densities on the film in response to the first RGB to XYZ mapping applicable to the monitor and in response to the second RGB to XYZ mapping applicable to the film recorder.
