Abstract:
1. An encoding apparatus for encoding element data in a multidimensional space expressed by M (M≧3) dimensions, comprising: an input unit configured to update a value α of an axis of one dimension of the multidimensional space in turn, and to input a two-dimensional data assemblage I(α) for each α; a generation unit configured to calculate element difference data indicating differences between element data which form the inputted data assemblage I(α) and elements which form an immediately preceding inputted data assemblage I(α−1) and to generate an element difference data assemblage D(α) formed by the element difference data; and an encoding unit configured to predictively encode the element difference data assemblage D(α) generated by said generation unit, wherein the element data in the multidimensional space to be encoded is a color lookup table included in color profile data for conversion between two different color spaces.
