ELECTRONIC ENDOSCOPE SYSTEM
First Claim
1. An electronic endoscope system, comprising:
- a light source device for sequentially emitting light having different wavelength bands;
an electronic endoscope for sequentially illuminating a subject tissue containing a blood vessel inside a body cavity with said light sequentially emitted from said light source device, receiving reflected light of said light from said subject tissue, and sequentially outputting image data of wavelength bands of said subject tissue corresponding to the different wavelength bands of said received reflected light;
blood vessel characteristics amount calculating means for calculating a blood vessel characteristics amount containing at least one of a blood vessel depth, a blood vessel diameter, a blood vessel density, a blood vessel branch point density, and a fluorescent agent distribution in said subject tissue from said image data of the wavelength bands;
oxygen saturation level calculation means for calculating an oxygen saturation level in said blood vessel of said subject tissue from said image data of the wavelength bands;
image producing means for producing a reference image of said subject tissue from said image data of the wavelength bands;
region-of-interest extraction means for extracting from said reference image a region of interest containing a predetermined blood vessel characteristics amount and a predetermined oxygen saturation level set by specifying information based on blood vessel characteristics amounts calculated in said subject tissue and oxygen saturation levels calculated in said blood vessel of said subject tissue;
enhanced image producing means for producing an enhanced image in which said region of interest is enhanced in said reference image; and
image displaying means for displaying said enhanced image.

Abstract
An electronic endoscope system includes a light source device, an electronic endoscope for sequentially illuminating a subject tissue containing a blood vessel inside a body cavity with the light, and sequentially outputting image data of wavelength bands of the subject tissue corresponding to the different wavelength bands of received reflected light, a calculator for calculating a blood vessel characteristics amount in a subject tissue from the image data, a calculator for calculating an oxygen saturation level in the blood vessel from the image data, an image producer for producing a reference image of the subject tissue from the image data, an extractor for extracting a region of interest from the reference image, a producer for producing an enhanced image, and a display for displaying the enhanced image.
