Claim One:
1. An electronic endoscope system comprising: a light source device for sequentially emitting plural kinds of light having different wavelength bands from each other; an electronic endoscope for sequentially illuminating the plural kinds of light emitted from said light source device to a subject tissue containing blood vessels inside a body cavity, sequentially receiving the plural kinds of reflected light of the illuminated light from the subject tissue, and sequentially outputting image data of acquired images corresponding to the plural kinds of received light having the different wavelength bands; blood vessel characteristics amount setting means for setting a blood vessel characteristics amount related to the blood vessel containing 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 of at least one of the acquired image outputted from said electronic endoscope; interest region setting means for setting a region of interest in the acquired image by said electronic endoscope based on the blood vessel characteristics amount calculated by said blood vessel characteristics amount setting means; image production means for producing a first oxygen saturation level image representing a distribution of an oxygen saturation level in the blood vessel in simulated color from the image data of the acquired images; and image display means for displaying in the simulated color a second oxygen saturation level image in which the oxygen saturation level within the region of interest set by said interest region setting means is selectively enhanced in the first oxygen saturation level image produced by said image production means.
