Abstract

撮影対象の光２がレンズ系３に入射し、その光はカラーフィルタ５において透過・吸収され、透過成分はイメージセンサー４に入射され、撮像される。カラーフィルタ５は、図７（ｂ）に示すように、透明画素（Ｗ）、等色関数Ｘの補色フィルタ（Ｗ－Ｘ）、等色関数Ｙの補色フィルタ（Ｗ－Ｙ）、等色関数Ｚの補色フィルタ（Ｗ－Ｚ）の微小なフィルタからなり、この一つ一つはイメージセンサーの各画素の位置と一致するよう配置される。結果として、全波長成分、Ｘの補色成分、Ｙの補色成分、Ｚの補色成分の光が各々の画素に入射され、撮像される。この撮像された像から、Ｗ－（Ｗ－Ｘ）、Ｗ－（Ｗ－Ｙ）、Ｗ－（Ｗ－Ｚ）を算出することで、ＸＹＺに対応した画像を再現し、忠実な色の撮影が可能になる。これにより正確な色彩値を、光利用効率を良く撮像することを特徴とすることができる。
