ABSTRACT:
An endoscope including a light source for generating light beams having difference wavelengths to an object in an internal organ such as the stomach and the intestines of a subject, in which picture signals are picked up by a pickup device such as an optoelectronic device from the object radiated with the light beams, in which correction signals such as reference picture signals for correcting sensitivities of the light source and the pickup device depending on the different wavelengths of the light beams are picked up by the pickup device from a reference member such as a reference white plate radiated with the same light beams, and in which a bloodstream amount and an oxygen saturation rate are operated from the picture signals and the correction signals. The bloodstream amount and the oxygen saturation rate may be displayed on a display. The correction signals may be picked up outside the body of the subject.
