Claim Text:
1. An electronic endoscope system, comprising: a light source that emits light having a visible light wavelength region; an optical filter that has transmission peaks at least at two particular wavelengths in a continuous wavelength region including the visible light wavelength region, a lower limit of transmissivity of the optical filter between the transmission peaks is higher than or equal to 5% of each transmission peak and an upper limit is lower than or equal to 10% of each transmission peak, in an interval between the transmission peaks of the at least two particular wavelengths, the optical filter having a transmissivity of zero at a wavelength region other than the interval between the transmission peaks of the at least two particular wavelengths; a solid-state image pick-up that receives reflected light from an object which is irradiated with illumination light via the optical filter; and an image generator configured to generate a color image to be displayed on a monitor by processing an image signal outputted by the solid-state image pick-up.
