Claims (4)
- 三角形のプリズムとレンズ及びイメージセンサーを含んで構成された光学指紋入力装置であって、
前記プリズムの3面中、指紋部位が接触する面に対して指紋の底面を照らすことができる方向に光を放射する光源と、
前記プリズムの指紋部位が接触しない残りの2面中、前記レンズと反対側に位置する面の識別表示と、
前記イメージセンサーに入力されるイメージを分析して、入力イメージに識別表示イメージが含まれているか否かを判別し、判別結果、識別表示イメージが含まれた場合は、該当入力イメージを残像として識別してエラーコードを発生する演算制御部と、
を含んでなることを特徴とする光学指紋入力装置。 - 前記識別表示は、前記レンズと反対側に位置するプリズムの面に付着され、光が透過できる材質のフィルム上に記入されることを特徴とする請求項1に記載の光学指紋入力装置。
- 前記光源の光と前記識別表示の色相は相互間に補色関係を有するように設定されることを特徴とする請求項1または2に記載の光学指紋入力装置。
- 前記プリズムは、指紋部位が接触する面からこれに垂直方向に位置する稜に繋がる垂線(PL)と前記プリズムから前記レンズ及び前記イメージセンサーを連結する光軸(OA)との間の角度が、前記指紋部位が接触する面に接触する指紋に付いた水や脂などの異質物に対するイメージ入力が防止できる実験値により求められる特定の角度で設定されることを特徴とする請求項1または2に記載の光学指紋入力装置。
