Abstract

A method, apparatus and programmed computer system for processing image data as picture screen elements having colour components are provided which generate a three-dimensional space representing a colour spectrum containing said colour components, initiate a plurality of three-dimensional space transformation matrices and concatenate said three-dimensional space transformation matrices to initiate a single three-dimensional space transformation matrix. Said plurality of three-dimensional space transformation matrices are populated in reply to user input data and said image data is adjusted by means of processing each of said colour components with said single three-dimensional space transformation matrix.
