摘要:
A light source control device for an endoscope having a light source for emitting light to be incident on a light guide, a stop mechanism for varying the quantity of light to be incident on the light guide by interrupting an optical path of light, and a control device for controlling an opening of the stop mechanism. The stop mechanism includes a sensing device for sensing the opening of the stop mechanism and outputting a sensing signal to the control device. Further, the stop mechanism includes a shaft and a stop blade rotatably supported on the shaft and being disposed in the optical path such that the quantity of light passing thereby is varied by rotating the blade. The sensing device includes an arc-shaped plate fixed to the shaft and having a radius which varies in proportion to the change in arc angle, and a sensor having an opening for receiving the circumferential edge of the arc-shaped plate to sense the amount of light which passes through the opening.

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.

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.

A scanning endoscope apparatus, comprising a first transmitter, an actuator, a first optical filter, a second optical filter, a second transmitter, a first photo-detection unit, and a position determiner, is provided. The first transmitter transmits light to a first emission end. The actuator moves the first emission end. The first optical filter reflects the light of the first band. The second optical filter transmits the light of the first band at a transmittance that varies according to the position. The second transmitter transmits the light of the first band from a second incident end to a second emission end. The first photo-detection unit detects an amount of the light of the first band. The position determiner determines a position of the first emission end on the basis of the amount of the light of the first band.

An electronic endoscope system, which is adapted to observe a fluorescence image of autofluorescence emitted from a body cavity wall irradiated with excitation light as well as a normal image of the body cavity wall illuminated with white light on a display device, includes a display controller whereby the aspect ratio of at least one of a plurality of images to display is converted so that the plurality of images are displayed in conformity with the shape of a display area of the display device when the plurality of images including the normal image and the fluorescence image are displayed on the display device. In the electronic endoscope system, the display controller converts the aspect ratio of at least one of the plurality of images by cutting both horizontal ends of the image to convert.
摘要:
An electronic endoscope selector is used in an electronic endoscope system which shares peripheral devices, such as a TV monitor, VCR etc., among a plurality of electronic endoscopes. The electronic endoscope selector includes switching circuits for switching and selecting video signals and synchronizing signals fed from one of the plurality of electronic endoscopes in the system. The selector also has ON/OFF switches and a timer. The ON/OFF switch controls output of the selected video signals. When the switching circuits switch between the plurality of electronic endoscope and switch video signals and synchronizing signals to that of a newly selected electronic endoscope, the output of video signals are suspended during a predetermined period, by the timer. The synchronizing signals are output simultaneously with the above switching.

摘要:
An electronic endoscope system that shares peripheral devices, such as a TV monitor, VCR etc., among a plurality of electronic endoscopes via an electronic endoscope selector. Each of the electronic endoscopes is connected to the electronic endoscope selector and the electronic endoscope selector selectively switches between video signals of the electronic endoscopes and feeds them to the TV monitor. Further the electronic endoscope selector comprises image memories and is able to store an image captured by the electronic endoscopes. A stored image may be comparatively displayed on the screen of the TV monitor with the live video being captured by the selected endoscope units. Further, the comparative display is controlled by control buttons on the electronic endoscope. The electronic endoscope selector also comprises a memory for storing image parameters for each electronic endoscope, and adjusts images on the screen by utilizing the parameter for each electronic endoscope.
摘要:
In a lightguide connector joint for an endoscopic system, the shape and dimensions of a lightguide connector (3) are determined in accordance with the size of the entrance end face (4a) of a lightguide (4) such that the smaller the size of the entrance end face (4a), the closer to the converging position of the rays of illuminating light is the position of the entrance end face (4a) that is established when the lightguide connector (3) is connected to a connector receptacle (20).
