Abstract: An endoscope includes, in a distal end frame constituting a distal end portion, an objective optical unit including a voice coil motor that moves a moving lens frame forward and backward in a direction of an optical axis by using a plurality of magnets arranged on a periphery of the moving lens frame, and a plurality of internal components made of magnetic material and arranged around the objective optical unit. At least one of the internal components is arranged at a position where at least a part thereof intersects one of straight lines each connecting an extreme point of one of valleys of a specific isomagnetic line of magnetic fields formed by the magnets and one of two inflection points of the specific isomagnetic line, the two inflection points being located, with the one of the valleys positioned between the two inflection points.

Abstract: An endoscope includes a first pulling section, an first elongated member, a restricting portion, a sliding surface, and a partition. The restricting portion is provided inside the operation section, and is configured to restrict a position of the first pulling section. The sliding surface is provided in the restricting portion, and allows the first pulling section to move along the axial direction. The partition covers at least a part of the sliding surface and the first pulling section, and is configured to partition the first elongated member and the first pulling section. The partition and the restricting portion are configured to restrict a moving range of the connection portion within a range of the sliding surface.

Abstract: An image processing device is configured to obtain first-type image data and second-type image data generated as a result of taking images of same photographic subject from different directions, and generate a parallax image based on the first-type image data and the second-type image data. The image processing device includes a processor comprising hardware. The processor is configured to: set an image selection mode in which an image is selectable based on an image displayed in a display; superimpose a frame data onto image data to be displayed in the display when the image selection mode is set, the frame data representing a boundary area whose size is set based on an optical system that forms an image of the photographic subject; and obtain the first-type image data and the second-type image data corresponding to selected image when the image selection mode is set.
