PROBLEM TO BE SOLVED: To provide an electronic endoscope system that enables simultaneous acquisition of both blood vessel depth information and oxygen saturation level information and selective display of an oxygen saturation level of a characteristic blood vessel portion that is of interest to an observer in making a diagnosis.SOLUTION: The electronic endoscope system includes: a light source device for sequentially emitting the light of different wavelength bands; an electronic endoscope for receiving the reflected light of the light sequentially emitted to a subject tissue and sequentially outputting image data corresponding to the wavelength bands; a setter for setting a blood vessel characteristics amount for calculating a blood vessel characteristics amount including at least one of a diameter of the blood vessel, a density of the blood vessel, and a branch point density of the blood vessel from the image data; a setter for setting a region of interest for setting a region of interest based on the blood vessel characteristics amount; an image producing means for producing an oxygen saturation level image representing a distribution of an oxygen saturation level in the blood vessel from the image data; and an image display for displaying in simulated color an oxygen saturation level image in which the region of interest is enhanced. |
