    • An endoscope apparatus has an illuminating device for applying at least infrared illuminating light to the interior of an organic body across the organic tissue of the body, an elongated insert portion to be inserted into the body, and an image pickup device having a light-receiving portion provided on an end of the insert portion and capable of picking up the infrared image of an object illuminated by the light transmitted through the tissue of the body. The endoscope apparatus further has an exposure amount control device capable of controlling the amount of exposure of the object by the illuminating device and applied to the object through the tissue of the body, and the amount of exposure of the object by illuminating light from another illuminating device which applies illuminating light to the object from inside of the body. The endoscope light source apparatus also comprises a body outside illuminating apparatus transmittively illuminating from outside the body the part observed with the endoscope. The exposure controlling apparatus controlling at least one of the exposure to the body inside illuminating light body from the body inside illuminating light source and the exposure to the outside illuminating light. The body outside illuminating light source can be made integral with the body inside illuminating light source and have a light transmitting member transmitting the light emitted from this body outside illuminating light source to a predetermined position outside the body and emitting it.
    • 内窥镜装置具有照射装置,用于至少将红外线照射光施加到有机体的内部,穿过身体的有机组织,插入身体的细长插入部分和具有光接收的图像拾取装置 部分设置在插入部分的端部上,并且能够拾取由透过身体组织的光照射的物体的红外图像。 所述内窥镜装置还具有曝光量控制装置,其能够通过所述照明装置控制所述物体的曝光量并且通过所述身体的组织施加到所述物体,并且通过照射来自另一照明的光的物体的曝光量 从身体内部向物体照射光的装置。 所述内窥镜用光源装置还具有从所述主体的外侧向所述内窥镜观察到的所述部件透射性地照射的身体外部照明装置。 曝光控制装置控制从照明光源内的身体向照明灯体内的身体的曝光和外部照明光的曝光中的至少一个。 照明光源外部的身体可以与照明光源内的身体一体形成,并且具有将从身体发射的照明光源的光发射到身体外部的预定位置并发射的透光构件。
