A method and a system for performing image processing functions, particularly for color image data, with a plurality of lookup tables (LUT's). For color image data, a CLUT (color lookup table) is prepared. These tables are prepared by performing the image processing functions on the values stored in the CLUT, such that each value for the processed image is retrieved by using the original pixel value for accessing a corresponding value in the CLUT. Since the processing of each color component may affect values of other color components, preferably a matrix of a plurality of CLUT's is used, with the number of rows and columns of the matrix equal to the number of different color components for each pixel of the image.
