Abstract
An endoscope apparatus includes an endoscope including an insertion portion which is insertable into a living body; an illumination section which emits illumination light to an observation target region side in the living body; a light amount control section which performs light amount control to at least decrease an amount of light in a red wavelength range in the illumination light which excites a photosensitizing substance which is administered to the observation target region; and a signal processing section which, in response to the light amount control, performs signal processing to increase a luminance level of a red color signal that corresponds to a red wavelength range in picking up an image under the illumination light.

An endoscope apparatus comprising:
- an endoscope including an insertion portion which is insertable into a living body;
- illumination means which emits illumination light to an observation target region side in the living body;
- light amount control means which performs light amount control to at least decrease an amount of light in a red wavelength range in the illumination light which excites a photosensitizing substance administered to the observation target region;
- and
- signal processing means which, in response to the light amount control to decrease the amount of the light in the red wavelength range, performs signal processing to increase a luminance level of a red color signal that corresponds to a red wavelength range in picking up an image under the illumination light.
An endoscope apparatus comprising:
- an endoscope including an insertion portion which is insertable into a living body;
- illumination means which emits illumination light to an observation target region side in the living body;
- light amount control means which controls an amount of light in a red wavelength range in the illumination light which causes production of reactive oxygen species by a photosensitizing substance which is administered to the observation target region;
- and
- signal processing means which, in response to the light amount control of the red wavelength range, performs signal processing to change a luminance level of a red color signal that corresponds to a red wavelength range in picking up an image under the illumination light.
