Description
図1は本発明の第1の実施の形態に係る撮像装置1の内部構成を示すブロック図である。
なお、本実施の形態では、遮光部材12と撮像素子16と別部材で形成したが、図6に示すように、撮像素子16の内部に遮光物を設けるようにしてもよい。なお、図6においては、簡単のため、撮像素子16として2個のフォトセンサが図示され、遮光部材12も2個のフォトセンサに対応した大きさで図示されているが、これらの光学要素はこれに限定されるものではない。実際には、被写体を撮影可能な任意の数や大きさの光学要素が設けられる。また、図2と同一の部分については、同一の符号を付し、説明を省略する。
また、本実施の形態では、撮影レンズ10を構成する所定のレンズの表面に遮光帯10cが形成して遠焦点領域10aを通過した光と近焦点領域10bを通過した光とが混合することを防止したが、遠焦点領域10aを通過した光と近焦点領域10bを通過した光とが混合することを防止する方法はこれに限られない。例えば、図7に示すように撮影レンズ内に瞳分割用の遮光部材を設けてもよい。
