Abstract
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 Gfilter section, Bfilter 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.
