Abstract
A method of transforming input image data into output image data in order to form an output image which comprises a plurality of specified image areas is provided. The method comprises providing a plurality of different sets of color transform look-up tables, associating the different sets of look-up tables with the plurality of specified image areas. The output data is coded to identify an associated one of the different sets of look-up tables responsive to one of the specified image areas for which the output data is being obtained. A color transformation is then performed on the input image data to obtain the output data using one of the different sets of look-up tables identified by the coding. An apparatus for carrying out the method is also provided.
