Abstract
An electronic endoscope system, including: 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 and has a transmissivity higher than zero and lower than a half of each transmission peak 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 an interval between the transmission peaks of the at least two particular wavelengths; a solid-state image pick-up device that receives reflected light from an object which is irradiated with illumination light via the optical filter; and an image generation unit 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 device.
