An endoscope system includes an endoscope, at least one monitor, a first measuring instrument configured to measure a first direction, at least one second measuring instrument configured to measure a second direction, a reception circuit configured to receive the image from the endoscope, and a processor. The first direction corresponds to a horizontal component of an imaging direction of the endoscope. The second direction corresponds to a horizontal component of a reference direction. The reference direction is a direction in which the at least one monitor faces or is a direction toward or away from an image display surface of the at least one monitor. The processor is configured to calculate an angle between the first direction and the second direction, process the image based on the angle, and display the processed image on the at least one monitor. The processing includes a rotation processing or a horizontal flip processing.

An image processing apparatus includes an inference part which is capable of inference by using a first inference model for finding of a specific target object and by using a second inference model for discrimination about the specific target object and a control unit to which a first picked-up image obtained under a first image pickup condition and a second picked-up image obtained under a second image pickup condition different from the first image pickup condition can be inputted and which performs control such that in a case where the first picked-up image is inputted, the inference part is caused to execute inference by using the first inference model, and in a case where the second picked-up image is inputted, the inference part is caused to execute inference by using the second inference model.

Image processing apparatus, image processing method, and endoscope apparatus

An endoscope apparatus includes an image pickup unit comprising a plurality of image pickup devices and an optical path dividing member for dividing an entering light beam into a plurality of optical paths, wherein respective optical path lengths are different from one another; a contrast comparing member for comparing contrasts of a plurality of images; an image selecting member for selecting and outputting only one image signal from one image pickup device among the plurality of image pickup devices, on a basis of comparison result by the contrast comparing member; and a driving member for moving a movable lens so that a difference among the contrasts of the plurality of images is largest, wherein a part of an objective lens is configured to be movable in an optical axis direction.

Endoscope apparatus

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.

Endoscope having breakable portions for preventing damage to the imaging unit

An image pickup unit includes a board to which an image pickup device is electrically connected, the board is provided with a first terminal portion which includes a plurality of terminals and is used when a first endoscope is configured, and a second terminal portion which includes a plurality of terminals and is used when a second endoscope is configured, a folding portion is provided between the first terminal portion and the second terminal portion of the board, when the board is used as an image pickup unit of the second endoscope, the board is folded at the folding portion, and a signal transmission member is connected to the second terminal portion, and at least one of a terminal size and a space between terminals in the second terminal portion is set to be larger than at least one of a terminal size and a terminal space in the first terminal portion.

Image pickup unit

An actuator has a magnet moved together with a moving lens frame, an SMA wire capable of extending and contracting in a moving direction I of the moving lens frame with execution or non-execution of energization thereof, a fixing member made of a magnetic material attached to a distal end of the SMA wire, a pressing spring which urges the fixing member toward the magnet along the moving direction I, and a stopper member and a stopper portion which limits the movement of the magnet along the moving direction I at a first position or a second position.
