Abstract
An electronic endoscope system includes a light source that emits light having a visible light wavelength region, and an optical filter that has transmission peaks at least at two particular wavelengths in a continuous wavelength region including the visible light wavelength region. The optical filter has a transmissivity that suppresses a light amount cut by the optical filter between the transmission peaks of the at least two particular wavelengths and has 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 receives reflected light from an object which is irradiated with illumination light via the optical filter and an image generator is configured to generate a color image to be displayed on a monitor by processing an image signal output by the solid-state image pick-up.
