Abstract: [Problem] Enabling suppressing of emission of unnecessary illumination light and concentrating the illumination light on a necessary region while suppressing the hindrance of user's movement. [Solution] There is provided a surgical observation device including: an imaging unit that captures an image of a surgical region being an observation target and thereby outputs a captured image; an irradiation unit that irradiates the surgical region with illumination light; an arm unit including a plurality of links and one or more joints connecting the plurality of links and configured to hold, at one end, the imaging unit and the irradiation unit; and a support unit connected to the other end of the arm unit and configured to support the arm unit, in which the support unit has a light source unit an irradiation optical system, the arm unit has an optical waveguide that guides a light beam emitted from the light source unit and passing through the irradiation optical system to the irradiation unit, and the irradiation optical system sets a variable irradiation range of the illumination light emitted by the irradiation unit.

Abstract: [Object] To make it possible to execute the insertion of an endoscope into an inside of an observation object more promptly, and to reduce the burden of an endoscope operator more.[Solution] An endoscope apparatus according to the present disclosure includes: an endoscope unit at least a part of which is inserted into an inside of an observation object and that propagates an image of the inside of the observation object irradiated with illumination light; a light source unit that emits the illumination light illuminating the inside of the observation object to the endoscope unit; an imaging unit that captures an image of the inside of the observation object having been propagated from the endoscope unit and generates a captured image of the inside of the observation object; and a control section that performs driving control for the endoscope unit, the light source unit, and the imaging unit. A radiation angle of the illumination light is changeable, and the control section changes the radiation angle of the illumination light in accordance with whether an insertion portion being a part of the endoscope unit having been inserted into the inside of the observation object is moving in the inside of the observation object or has stopped.
