Summary:To prepare a color matching function for plural different observation visual fields at lower costs than when creating it entirely by an experiment.SOLUTION: A color matching function (namely, a base function) that becomes a base is input to a base function input part 10. Two color matching functions having different observation visual fields are input to a reference function input part 12 as reference functions. In the reference functions, at least one of creation conditions other than the observation visual fields differs from that of the base function. A comparison part 14 compares two reference functions and generates, for example, a comparison result function for indicating a comparison of or a difference in both of them. A composite part 16 generates a new color matching function by compositing (for example, by multiplication for a comparison result function for indicating a ratio) comparison result functions to the base function. The new color matching function has a different observation visual field as compared with the base function.SELECTED DRAWING: Figure 1 【課題】異なる複数の観察視野についての等色関数を、すべて実験により作成する場合と比べて、より低コストで用意する。【解決手段】ベース関数入力部１０に対して、ベースとなる等色関数（すなわちベース関数）が入力される。参照関数入力部１２に対して、観察視野が異なる２つの等色関数が参照関数として入力される。それら参照関数は、観察視野以外の作成条件のうちの１以上が、ベース関数と異なる。比較部１４は、２つの参照関数を比較し、例えばそれら両者の比率又は差分を示す比較結果関数を生成する。合成部１６は、ベース関数に対して比較結果関数を合成（例えば比率を示す比較結果関数の場合は乗算）することで、新たな等色関数を生成する。この新たな等色関数は、ベース関数に対して観察視野が異なるものである。【選択図】図１
