Description
図1は、この発明の実施の形態1にかかるカプセル型内視鏡を含む無線型被検体内情報取得システムの全体構成を示す模式図である。図1において、無線型被検体内情報取得システムは、無線受信機能を有する受信装置2と、被検体1内に導入され、体腔内画像を撮像して受信装置2に対して画像信号などのデータ送信を行うカプセル型内視鏡3とを備える。また、無線型被検体内情報取得システムは、受信装置2が受信した画像信号に基づいて体腔内画像を表示する表示装置4と、受信装置2と表示装置4との間でデータの受け渡しを行うための携帯型記録媒体5とを備える。
つぎに、この発明の実施の形態2について説明する。上述した実施の形態1では、電源回路22から供給される電力と電力蓄積部23から供給される電力との総電力を、各LED11に均等に配分するようにしていたが、この実施の形態2では、電源回路22から供給される電力によって発光するLED11と電力蓄積部23から供給される電力によって発光するLED11とに分割して電力配分するようにしている。
