Abstract:
1. An endoscopic device comprising: an endoscope comprising an image pickup unit for picking up an image of a subject and outputting the picked up image of the subject as an image pickup signal; an image pickup signal amplification unit for amplifying the image pickup signal; a light source unit for emitting first illumination light having at least a visible region band to the subject; a light intensity control unit for controlling an amount of light emitted from the light source unit, the light intensity control unit comprising: a spectral unit, having predetermined spectral characteristics, for penetrating a light in a band based on the predetermined spectral characteristics among the lights emitted from the light source unit when arranged on the optical path of the light source unit; a brightness control unit for controlling a brightness of an image generated based on the image pickup signal and displayed on a display unit; and a mode switching unit for switching a first mode in which the spectral unit is removed from the optical path of the light source unit to emit the first illumination light to the subject and a second mode in which the spectral unit is arranged on the optical path of the light source unit to emit the second illumination light having a band narrower than the first illumination light to the subject, wherein the brightness control unit, in the second mode,
