〔カプセル型内視鏡システムの概略構成〕
図1は、本発明の参考例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1について説明する。本実施の形態1は、上述した参考例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1に係る光源部の構成を説明する。なお、上述した参考例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1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2について説明する。本実施の形態2は、上述した参考例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2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、上述した参考例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。
