摘要： A light source apparatus includes a first rotational filter section that can place a blue filter, a green filter and a magenta filter in a light path, a second rotational filter section that can place a yellow filter in the light path and a band selection filter section that can place an NBI filter that limits blue and green light to a narrow band, wherein the first and the second rotational filter sections are controllable so that in the case of normal light imaging, the yellow filter is placed in the light path when the magenta filter is placed in the light path and in the case of narrow band imaging, the NBI filter is placed in the light path LP and the yellow filter is placed in the light path when the green filter is placed in the light path.
