Description
前記入力したカラー画像の各画素の色情報の配色組み合わせを検索し
当該配色組み合わせが、色覚異常者にとって混同しやすいか否かを検出する手段と、
前記カラー画像に用いられている色を複数の前記混同しやすい色及び当該混同しやすい色に近似する色からなる色組に分けてクラスタ化し、クラスタ中の前記色覚異常者にとって混同しやすい色の当該クラスタに占める比率が閾値以上の時にクラスタ内の全ての画素の色を修正する手段と、
を有することを特徴とする色修正装置である。
(池田光男,中嶋芳雄「色覚のメカニズムと色覚異常」眼科Mook No.16 1982)
以下に、図を参照して、本発明の色修正装置の例を説明する。
最後に、ステップ7で修正された画像を表示若しくは印字(ステップ8)し、確認評価を行う(ステップ9)。評価の結果、パラメータを再度制御して、繰り返し調整を行うことも可能となる。
