AbstractAn object is illuminated sequentially with light of wavelengths in respective narrow bands through a light guide in an electronic endoscope provided with an imaging device. The picture images are photoelectrically converted by the imaging device and are temporarily stored respectively in memories. The spectral distribution characteristics of the object are calculated by using spectral distribution calculating data and are displayed on a display.
