Endoscopic system includes: that light supply apparatus has the ability to supply exciting light and generate fluorescence,The different wave band of reference light is from fluorescence,The optical system of object lens,The optical filter is configured to prevent the exciting light of reflection,Image pickup section,It is configured to separate,And it picks up,Light,I.e.,Fluorescence is emitted to by optical filter,Light first wave length frequency band,Light and second wave length band,Observation image generating unit distribution sets to generate the pickup fluorescence for the signal that observation image is obtained by first to third,First band of light,With the light of second band,And control unit,It is configured as making the first signal,For distributing to the display device of green component,And make to be had between relative signal value by signal,Second and third control signal,For distributing to the display device of red component,Signal has relatively small signal value,For distributing to the display device of blue component.
