    摘要: In an endoscope apparatus of the present invention, while observing a body cavity tissue under narrowband light via a second filter group of a rotating filter, a G2 filter section, B2 filter section, and shading filter section change illumination light to narrowband surface-sequential light of two bands of discrete spectral characteristics, and an image-capturing signal captured by a CCD via the B filter section constitutes a band image having superficial layer tissue information, and an image-capturing signal captured by a CCD via the G filter section constitutes a band image having intermediate layer tissue information. This produces tissue information of a desired depth in the vicinity of a superficial portion of a mucous membrane using an inexpensive and simple configuration.

    摘要: By disposing a plurality of magnetic-field generating elements in the inserted portion of an endoscope, and by detecting it using a magnetic-field detecting unit disposed around the inserted portion, the shape of the inserted portion inserted into a body cavity is detected and it is displayed on a display device. For this purpose, it is determined whether the inserted portion is in an effective detection range in which the insertion portion shape can be detected by a detecting unit with a practicable accuracy, and by changing the display color of the inserted portion shape based on the determination result, it can be easily checked whether the inserted portion is in the effective detection range.
