Abstract
An electronic endo scope system includes a light source that emits light including at least a visible light band, an optical filter that has a transmittance peak at a particular wavelength within a continuous wavelength band including at least the visible light band and that has a transmittance distribution which is based on the transmittance peak within an entire of the continuous wavelength band except the transmittance peak, an optical filter switching unit that inserts and retracts the optical filter into and out of an illumination optical path of the light source, a color solid state image pick-up device that receives reflected light from a subject illuminated with illumination light which has passed, or not passed, through the optical filter, and an image generating unit that generates a color image displayable on a monitor by processing an imaging signal output by the solid state image pick-up device.
