〔カプセル型内視鏡システムの概略構成〕
図1は、本発明の実施の形態1に係るカプセル型内視鏡システムの概略構成を示す模式図である。
次に、図1で説明したカプセル型内視鏡2の詳細な構成について説明する。図2は、カプセル型内視鏡2の機能構成を示すブロック図である。
次に、本発明の実施の形態2について説明する。本実施の形態2は、上述した実施の形態1と光源部の構成のみが異なる。このため、以下においては、本実施の形態2に係る光源部の構成を説明する。なお、上述した実施の形態1に係る構成と同一の構成には同一の符号を付して説明を省略する。
図7は、本実施の形態2の変形例に係る光源部の構成を示す模式図である。図7に示す光源部24bは、特殊光源241と、第1光源243と、第2光源244と、第3光源245と、を有する。
次に、本発明の実施の形態3について説明する。本実施の形態3は、上述した実施の形態1に係るカラーフィルタおよび光源部の構成が異なる。このため、以下においては、本実施の形態3に係るカラーフィルタおよび光源部の構成について説明する。なお、上述した実施の形態1と同一の構成には同一の符号を付して説明を省略する。
本発明では、カラーフィルタが原色フィルタで構成されていたが、例えば補色の波長成分を有する光を透過する補色フィルタ(Cy,Mg,Ye)を用いてもよい。さらに、カラーフィルタを、原色フィルタと、オレンジおよびシアンの波長成分を有する光を透過するフィルタ(Or,Cy)とによって構成されたカラーフィルタ(R,G,B,Or,Cy)を用いてもよい。さらにまた、原色フィルタと、白色の波長成分を有する光を透過させるフィルタ(W)とによって構成されたカラーフィルタ(R,G,B,W)を用いてもよい。
