Even if the characteristics of a light source device and an endoscope scope vary, and in any combination of a plurality of light sources and scopes, calibration is performed by a small and low-cost measuring means, thereby An endoscope system that is not affected by color reproducibility or resolution is provided. A light source device that irradiates light in a predetermined wavelength band, and irradiates a subject tissue in a body cavity with white light generated by irradiating the irradiated light with a phosphor as excitation light, and photoelectrically reflects the reflected light. Electronic endoscope having an image sensor that converts and outputs image data, wavelength detection means for detecting the wavelength of the irradiated light, and wavelength shift that is the difference between the detected wavelength and a preset reference wavelength A wavelength shift amount calculating means for calculating the amount, a first correction means for correcting the amount of light emitted from the light source device, and a gain of photoelectric conversion by the image sensor in accordance with the calculated wavelength shift amount. Second correction means. [Selection] Figure 2 |
