An endoscope system includes: an endoscope configured to have a field of view in front of a distal end portion of an insertion portion having flexibility and an elongated shape; an insertion assisting instrument including a conduit having an inner portion through which the insertion portion can be inserted, and the insertion assisting instrument being configured to enable an angle of a distal end portion of the conduit to be changed; an image generation section that generates an image corresponding to the field of view of the endoscope and outputs the generated image; a rotation angle calculation section that calculates a rotation angle indicating to what extent an orientation of the image is rotated with respect to a reference direction, the image being outputted from the image generation section when at least a part of the insertion portion is inserted through the conduit; and an image rotation section that performs image rotation processing on the image outputted from the image generation section, for displaying, on a display screen of a display section, the image with the rotation angle being offset. |
