An optical connector which enables an operator to easily remove a ferrule from a housing without using a special jig by himself alone. A supporting member that is mounted in a housing in a manner capable of being inserted and removed in a state in which the ferrule is held therein, includes a supporting member main body which is accommodated in the housing, and an operating portion which temporarily releases an engagement between protrusions formed on the supporting member main body and through holes formed in the housing. The operating portion is arranged in a manner protruding outside the housing when the supporting member is mounted in the housing.

An electronic endoscope has a video-scope with an image sensor, a light source that emits illuminating-light to illuminate an object, an image sensor driver, a luminance detector, one rotary shutter, and a brightness adjuster. The luminance detector detects a luminance of an object image on the basis of image-pixel signals read from the image sensor. The rotary shutter has a light-transmitting portion that transmits the illuminating light, and a shield portion that blocks the illuminating light. The brightness adjuster controls the rotary shutter to adjust an irradiation-interval of the illuminating-light in accordance with a charge accumulation interval. The brightness adjuster shifts a rotation-phase of the rotary shutter by changing a rotation-speed on the basis of the detected luminance, so as to maintain a brightness of the object image at a proper brightness.

An electronic endoscope system for observing living tissues inside a body cavity includes an illuminating apparatus having a white light source emitting white light and an excitation light source emitting excitation light, an electronic endoscope including an insertion part to be inserted into the body cavity, an imaging device that receives an optical image and outputs image signals corresponding to the optical image, an image forming system that forms the optical image, an operating pant provided at a rear anchor of the insertion part, and a plurality of operable members arranged at the operating part, a display device, an image processing system that receives the image signals outputted from the imaging device, the image processing system obtaining a normal image when the living tissues are illuminated with the white light and a fluorescence image when the living tissues are irradiated with the excitation light, and a control system that controls the whole of the electronic endoscope system. The control system assigns a function to one of the plurality of operable members for switching between a normal mode for observing the normal image and a fluorescence mode for observing the fluorescence image. The control system assigns different functions between the normal mode and fluorescence mode to at least one of the others of the plurality of operable members.

A scanning endoscope, comprising a first transmitter, an actuator, and a mirror, is provided. The first transmitter emits a beam of radiant light from the first emission end. The actuator moves the first emission end in a direction perpendicular to an emission direction. The mirror is arranged from the first emission end to the first direction. The mirror comprises a through-part and a reflection surface. The radiant light emitted from the first emission end passes through the through-part when the first emission end is within a first circumference. The reflection surface reflects the radiant light emitted from the first emission end toward the observation area around the first straight line when the first emission end is outside of the first circumference.

An endoscope shape monitoring system that is used to grasp a shape of a flexible insertion portion is provided that includes a position detector and a determining processor. The position detector detects a plurality of positions of the insertion portion along the central axis of the insertion portion at predetermined intervals. The determining processor determines the position of at least one of the central axis or an outline of the insertion portion.

A scanning endoscope, comprising a first transmitter, an actuator, and a mirror, is provided. The first transmitter emits a beam of radiant light from an emission end. The actuator moves the emission end in a direction perpendicular to an emission direction. The mirror is arranged from the emission end in the emission direction when the emission end is on a predetermined standard point. The mirror comprises a reflection surface around a first straight line. The distance between a first position on the first straight line to any second position on the reflection surface increases as the first position is moved in the first direction. The reflection surface reflects the radiant light emitted from the first transmitter toward the observation area around the first straight line.

An endoscope apparatus, comprising an imaging controller, a receiver, and an image generator, is provided. The imaging controller makes an optical image to be captured so that the amount of optical information to be captured per a certain area size for an enlarged observation area is greater than that for a normal observation area. The receiver receives the optical information as a pixel signal. The image generator generates a normal image signal corresponding to a normal image on the basis of the pixel signals captured within the normal observation area and a part of the pixel signals captured within the enlarged observation area. The image generator generates an enlarged image signal corresponding to an enlarged image on the basis of the pixel signals captured within the enlarged observation area.

An endoscope shape monitoring system that is used to grasp a shape of a flexible insertion portion is provided. The endoscope shape monitoring system includes a plurality of coils. The coils are used as a magnetic sensor. The coils are disposed on a flexible portion of the insertion portion. The plurality of coils are arranged at positions where the coils are not subjected to a bending stress that is induced when the flexible portion is bent.

An endoscope-shape monitoring system is provided that is used to grasp a shape of a flexible insertion portion. The endoscope-shape monitoring system includes a position detecting system, a bending determinator, and a bendable-portion-shape reproducing processor. The position detecting system detects positions of both ends of a bendable portion of the insertion portion. The bending determinator determines a bending situation of the bendable portion. The bendable-portion-shape reproducing processor reproduces the shape of the bendable portion in accordance with the positions and the bending situation.
