Abstract: An endoscope system includes: an insertion portion; a first image acquisition portion; second image acquisition portions; and an image generation portion that, when displaying a first object image and second object images on a monitor in a manner in which the second object images are caused to be displayed adjacently to the first object image on both sides thereof, generates image signals that express perspective by performing image processing that makes a magnification of the second object images higher than a magnification of the first object image so that an image height of regions towards sides that are away from the first object image in the second object images gradually increases relative to an image height of regions that are adjacent to the first object image in the second object images.

Abstract: A flexible tube insertion support apparatus includes a generation section configured to generate propriety information regarding a propriety of a twisting operation of a flexible tube in accordance with a force quantity of an external force applied to the flexible tube when the flexible tube is twisted in a counterclockwise direction or a clockwise direction around a central axis of the flexible tube. The external force is detected by at least one external force detector that is disposed on the flexible tube to be inserted into the subject and configured to detect the external force. The flexible tube insertion support apparatus also includes an output section configured to output the propriety information generated by the generation section.

Abstract: In a flexible tube insertion apparatus, at least one circuit determines whether an S-shape is formed in an insertion section based on a shape information of the insertion section detected by a detector, determines whether an intersection angle between an extension line of a central axis of the insertion section and a tangential line for the insertion section at an inflection point is enlarged or not based on the shape information, and determines whether or not the stiffness variable portions are provided in a position of the S-shape in the insertion section when it is determined that the S-shape is formed and the intersection angle is enlarged. A stiffness controller increases a stiffness of the stiffness variable portions included in the position of the S-shape in accordance with the determination of the circuit.

Abstract: An flexible tube insertion apparatus includes a tubular insertion section including a bending portion and a flexible tube portion, variable stiffness sections to cause a change in a level of a bending stiffness of the flexible tube portion, a variable stiffness control section that controls the change in the bending stiffness by the variable stiffness sections; and a time setting section that sets a time period. The variable stiffness control section causes the bending stiffness of the variable stiffness sections to change in such a manner that the relationship of levels between the bending stiffness of adjacent variable stiffness sections is switched at the set time period when the variable stiffness control section determines that the flexible tube portion is passing through a flexure of the subject.
