Apparatus and method for converting color signal, and computer-readable recording medium for storing computer program for controlling the apparatus

摘要

An apparatus and a method for converting a color signal and a computer-readable recording medium storing a computer program for controlling the apparatus. The apparatus converts an input color signal including first through m^th input color components into an output color signal including first through n^th (n>m) output color components. The apparatus includes: a combination extractor which extracts combinations for the first through n^th output color components; a coefficient generator which generates a coefficient for representing the input color signal using the input color signal and the extracted combinations; a combination selector which selects desired combinations among the extracted combinations using the coefficient; and an output unit which generates the output color signal using the selected combinations.
