Title: ENDOSCOPE SYSTEM
Abstract:
This endoscope system is provided with: a light source which emits first light; a rotating plate in which a first light passing region through which the first light is allowed to pass, and a second light passing region which extracts second light in one or more types of specific wavelength region from the first light, are disposed side-by-side in a prescribed direction, wherein the first light passing region is configured in such a way as to reduce a difference between the amount of first light that passes through the first light passing region and the amount of second light extracted by means of the second light passing region; a rotary drive unit which causes the rotating plate to rotate, thereby successively causing the first light passing region and the second light passing region to be inserted into an optical path of the first light from the light source; a shift drive unit which causes the rotating plate to shift in a direction intersecting the optical path from the light source; and a control unit which controls a shift drive means in such a way that the ratio between the amount of light that has passed through the second light passing region and the amount of light that has passed through the first light passing region falls within a standard range.
