      錯視や錯覚の知識を「人間の知覚が全般にいいかげんである証拠」と考えるのは危険で、実際には知覚は基本的に世界を(物理的にも)正しく捉えているのだけれど、錯視は世界を正しく捉えるための機構が誤動作した少数例と考えるべきラジよ。

      錯視には、そういう例は多いですよね。何のなれの果てなのかわからないものも、未だ多いですが。pic.twitter.com/VFYyHXLv0f

      人間のこれがうまく働いて役に立ってたのはいつごろなんだろうという比較知覚心理学がなりたつんですね。

      私はそれ錯視ではなく視覚の正常な補正機能だと思います。https://twitter.com/kabutoyama_taro/status/838982474231263232 …

      実際、RGBのRを強調する補正をかませば、この程度には復元できてしまう、と。 この程度の補正が人間の知覚で行なわれるのは当たり前といえば当たり前ぐらいにしか思わないなあ。 pic.twitter.com/hdq4nboNLr

      色の恒常性(color constancy)と言います。おっしゃる通り、機能的です。一方、「画素は赤くないのに赤く見える」と表現すれば、色の錯視です。

          はい。なので私は、見方を変えれば錯視だとすることに違和感が。https://twitter.com/kabutoyama_taro/status/838990202471227392 …

          なにせこれ、「赤は含まれていないのに」とするのはさすがにミスリーディングで、元々沢山含まれる赤成分を、フィルター(背景)色を引き算する形で取り出すことができるのが色の恒常性、と言うべきなんだろうと思う。 赤が含まれなければ、何をどうしようと赤く見えることはないわけなので。
