Abstract
A color values processing description which represents a procedure of color values processing is analyzed by use of a partial reservation table and a total reservation table. The color values processing description is changed based on results of the analysis. For example, two consecutive operations of the same type, such as normalizing operations, gamma correcting operations or look-up table referencing operations, are unified into a single operation.
