An endoscope apparatus includes a distance information acquisition section that detects the position of a treatment tool and the position of a specific part, and acquires distance information about a distance between the specific part and the treatment tool based on the detected position of the treatment tool and the detected position of the specific part, a degree-of-closeness acquisition section that acquires the degree of closeness between the specific part and the treatment tool based on the distance information, and a treatment tool control section that controls at least one of an incision-related setting and a bleeding arrest-related setting of the treatment tool based on the degree of closeness.
