In the endoscope device of the present invention, the G2 filter part, the B2 filter part, and the light-shielding filter part at the time of observing narrow band light of tissue in the body cavity by the second filter set of the rotary filter are illumination bands of narrow band of two bands of discrete spectral characteristics. The imaging signal imaged by the CCD by the B2 filter portion becomes a band image having the structure information in the shallow layer, and the imaging signal imaged by the CCD by the G2 filter portion has the structure information in the middle layer. It becomes a band image. Thereby, the structure information of the desired core part vicinity of an adhesion surface layer is acquired by a cheap and simple structure. |
