An endoscope apparatus whereby the observing wavelength range can be selected in response to an object to be observed has a light source part emitting a light illuminating the object. An endoscope body has an elongated insertable part having an observing window and illuminating window in the tip part, a light transmitter transmitting the light of the light source part and emitting the light to the object from the illuminating window and an image forming optical system receiving the returning light from the object entering through the observing window and forming an object image. The object image formed by the image forming optical system is imaged on a solid state imaging device. An electric signal is output from the solid state imaging device and is processed by a signal processing circuit and a picture image is displayed. The object image is separated into a plurality of wavelength ranges by wavelength range separating filters. A selecting apparatus selects a picture image based on the wavelength range clearly representing the state of the object from among the picture images obtained by a plurality of separated wavelength ranges.
