Abstract: A medical apparatus system includes: an image generating section that generates an image in an observation field of view obtained from an observing section including an objective lens; an information collecting section that collects information of a treatment instrument; a distortion setting section that sets virtual distortion on the outside of the observation field of view from a characteristic of distortion of the objective lens; a distorted image generating section that generates a distorted image on the outside of the observation field of view with respect to the treatment instrument; and an image combining section that generates a combined image such that an image of the treatment instrument on the inside of the observation field of view and a distorted image of the treatment instrument coincide with each other in a boundary of the observation field of view.

Abstract: An endoscope includes a driving portion which drives a bending portion and a degree of displacement calculating portion which calculates a degree of displacement of a distal end of the insertion portion when the distal end of the insertion portion is displaced by reaction force generated by a movement of a distal end of a surgical instrument projecting from the distal end of the insertion portion. The endoscope further includes a control portion which controls a driving amount of the driving portion to eliminate the displacement in accordance with the degree of displacement calculated by the degree of displacement calculating portion.
