摘要:
An endoscope system or an endoscopic operation training system includes: projectors 12 and 13 which project video light indicating a video taken by an endoscope device that allows at least a part thereof to be inserted into patients body cavity and a dome type screen 11 having a shape of a projection surface 11a that directs a concave surface toward an operator and assistants, in which the video light is projected onto the projection surface 11a. In a case where an axis that passes through a center of an opening surface thereof and is perpendicular to the opening surface is defined as a first axis, a point where the first axis and the projection surface 11a intersect each other is defined as a projection surface center, and an axis that connects the projection surface center and an edge portion of the projection surface 11a to each other is defined as a second axis, and a tangential line of the edge portion of the projection surface 11a is defined as a third axis, then an angle made by the first axis and the third axis is an angle at which it is possible to observe a whole of the video from the first viewpoint position, and an angle made by the first axis and the second axis is an axis at which it is possible to observe the projection surface center from the second viewpoint position.
