## 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

### Claim 1

An endoscope system comprising:
an endoscope including an image pickup sensor configured to pick up an image of an object;
an illumination lens configured to irradiate the object with illumination light;
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; and
a processor including hardware, the processor being configured to:
control an illumination light intensity and an irradiation time period from the illumination lens;
control a gain of an image pickup signal outputted from the image pickup sensor;
detect whether or not halation relating to the object is generated when the aiming monochromatic laser beam is radiated; and
where generation of the halation by the aiming monochromatic laser beam is detected, perform a control to lower a color gain of a color component of the illumination light that is same as a color component of the aiming monochromatic laser beam, and perform a control to raise a light quantity of the illumination light including a wavelength of the aiming monochromatic laser beam.
