ABSTRACT:
A color conversion system is disclosed for converting raw RGB scanner data into a colorimetric system. The raw scanner data are processed in three stages. In the first stage, the raw RGB signals are converted into END-like RGB signals. This transformation is performed by passing each RGB signal separately through a lookup table to transform it to the equivalent END signal. In the second stage, the END signals are transformed into tristimulus signals XYZ. In the final stage, the XYZ signals are subjected to a non-linear transformation to convert them into a colorimetric system.
