Title:
ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/037505
Kind Code:
A1
Abstract:
This endoscope system is provided with: a light source device which repeatedly emits, in a prescribed order and as illumination light for illuminating biological tissue, a reference light and multiple special lights, in different wavelength regions; an imaging element which generates color image data of an image of the biological tissue illuminated with the aforementioned illumination light; a processor which is provided with a feature value acquisition unit that uses the aforementioned color image data to calculate oxygen saturation of hemoglobin in the biological tissue; and a display which displays an image of the biological tissue and a distribution image of the oxygen saturation. Regarding the order of the illumination light in one cycle, emission of the reference light between one emission of the aforementioned special light and another emission of the special light is carried out by the light source device at least twice, without continuous emission of the reference light.
