Abstract: In an endoscope bending tube provided in a bending portion of an endoscope in which a first bending tube region and a second bending tube region are arranged, a slit width of a plurality of bending slits arranged in the bending tube region is set to be smaller than a slit width of a plurality of bending slits arranged in the bending tube region, a width of the bending slits on the distal end side between the neighboring bending slits is set to be smaller than a width of the slits on the proximal end side, and an interval between the neighboring bending slits of a slit row in the bending region located on the distal end side is set to be smaller than an interval between the neighboring bending slits of the slit row in the bending region located on the proximal end side.

Abstract: An endoscope includes: an operation portion including a grasping portion configured to be grasped by a user and having a first longitudinal axis; an insertion portion configured to be inserted into a subject, the insertion portion having a second longitudinal axis that has a predetermined acute angle with respect to the first longitudinal axis and extending from the operation portion at a position on a more distal end side with respect to a treatment instrument insertion portion provided at the grasping portion; and a cable including, at an extension end thereof, a connector portion configured to be detachably connected with an external device, the cable having a third longitudinal axis on an extended line of the first longitudinal axis and extending from a distal end side of the operation portion.

Abstract: An endoscope includes a first breakable portion provided between a part of an outer peripheral surface of a distal rigid section main body and a second inner peripheral surface, and including a fragile portion which is formed in a concaved-shape and which is more easy to break than any other part of the outer peripheral surface except for thereof. The endoscope includes a second breakable portion provided between a first inner peripheral surface and the second inner peripheral surface, and a third breakable portion provided between the first inner peripheral surface and a part of the outer peripheral surface of the distal rigid section main body, which differs from the fragile portion.

Abstract: An image processing apparatus includes an obtaining unit, an area setting unit, and an adding unit. The obtaining unit obtains an adding method by which additional information is to be added to image data containing content information. The area setting unit sets an additional-information area to which the additional information is to be added based on the adding method and the content information. The adding unit adds the additional information to the additional-information area by the adding method.

Abstract: An image processing apparatus configured to embed embedment information in image data includes an embedment information acquisition unit configured to acquire embedment information to be embedded in the image data, an information embedment manner determination unit configured to determine an information embedment manner to embed the embedment information according to one of the acquired embedment information and image data to be generated by embedding the acquired embedment information in the image data, and an information embedment unit configured to embed the acquired embedment information in image data according to the information embedment manner determined by the information embedment manner determination unit.

Abstract: An image processing device including an area generation unit configured to generate a supplemental data-embedded area in image data having content data separate from an area occupied by the content data, and a data embedding unit configured to embed supplemental data in the supplemental data-embedded area.

Abstract: A cleaning brush which is inserted into a conduit of the endoscope, includes a long and flexible shaft, and a brush part provided at a leading end of the shaft. The brush part includes brush bristles, a strand, etc. A part of the shaft that overlaps the brush bristles in a state where the brush bristles are bent toward the leading end of the shaft, is provided with a small diameter part that is smaller in external diameter than the other part of the shaft. The dimension obtained by adding the external diameter of the small diameter part and twice the external diameter of the brush bristles is smaller than the internal diameter of a conduit into which this cleaning brush is inserted.
