PROBLEM TO BE SOLVED: To provide an endoscope apparatus which enables judgement of presence or absence of a blood vessel in the interior of the inner wall of a body cavity, a bone, etc., by acquiring a reflected light image of the inner wall of the body cavity etc.SOLUTION: The endoscope apparatus 1 includes an insertion part 11 which is inserted into the body and a control part 31 which is connected to the insertion part 11 and disposed outside the body. In the insertion part 11, a first light source part 12 radiating white light from the tip of the insertion part 11 to a surface area to be observed, and a first imaging part 13 acquiring the reflected light image of the surface area to be observed which is irradiated by the white light, are disposed. A second light source part 14 which emits near infrared light from the tip of the insertion part 11 to a region to be irradiated being located in the interior of the surface area to be observed, and a second imaging part 15 which detects the near infrared light reflected and/or scattered by the region to be irradiated and reaching the tip of the insertion part 11, are disposed in the insertion part 11, while the control part 31 acquires a change with time of the intensity of the near infrared light detected by the second imaging part 15.COPYRIGHT: (C)2013,JPO&INPIT【課題】 体腔内壁等の反射光像を取得して、体腔内壁や骨等の奥における血管の有無を判断することができる内視鏡装置を提供する。【解決手段】 体内に挿入される挿入部11と、挿入部11と連結され、体外に配置される制御部31とを備え、挿入部11には、挿入部11の先端から被観察表面領域に向かって白色光を照射する第一光源部12と、白色光が照射された被観察表面領域の反射光像を取得する第一撮像部13とが配置された内視鏡装置1であって、挿入部11には、挿入部11の先端から被観察表面領域の奥となる被照射部位に向かって近赤外光を出射する第二光源部14と、被照射部位から反射及び/又は散乱して挿入部11の先端に到達する近赤外光を検出する第二撮像部15とが配置され、制御部31は、第二撮像部15で検出された近赤外光の強度の時間変化を取得する。【選択図】図2
