Abstract

An endoscope system includes an endoscope, an illumination portion, a light adjustment portion, an insertion channel configured to allow insertion of a laser probe capable of radiating an aiming monochromatic laser beam, a gain control portion, a halation detection portion, and a control portion, and in a case that halation by the aiming monochromatic laser beam is detected in the halation detection portion, the control portion controls the light adjustment portion to adjust the illumination light and controls the gain control portion to control the gain.

Claims

1. An endoscope system comprising:

an endoscope including an image pickup device configured to pick up an image of an object;

an illumination portion configured to irradiate the object with illumination light;

a light adjustment portion configured to control illumination light intensity and irradiation time period from the illumination portion;

an insertion channel provided in the endoscope and configured to allow insertion of at least a laser probe capable of irradiating a predetermined position of the object with an aiming monochromatic laser beam for confirming a laser irradiation position;

a gain control portion configured to control a gain of an image pickup signal outputted from the image pickup device;

a halation detection portion configured to detect halation relating to the object when the aiming monochromatic laser beam is radiated; and

a control portion configured to control at least the light adjustment portion and the gain control portion,

wherein, in a case that the halation by the aiming monochromatic laser beam is detected in the halation detection portion, the control portion controls the light adjustment portion to adjust the illumination light and controls the gain control portion to control the gain.

2. The endoscope system according to claim 1,

wherein the control portion controls the light adjustment portion and the gain control portion to lower the gain of the image pickup signal and to raise brightness of the illumination light.

3. The endoscope system according to claim 1,

wherein the control portion controls the light adjustment portion and the gain control portion to lower a color gain of a same color component of the aiming monochromatic laser beam and to raise a light quantity of the illumination light that is the illumination light including at least a wavelength of the aiming monochromatic laser beam.
