    摘要: An endoscope insertion controlling apparatus includes a region extracting apparatus for extracting a plurality of regions corresponding to brightness from an endoscope image, for example, by setting a plurality of threshold levels of brightness and a judging apparatus for determining endoscope inserting conditions such as an inserting direction and progress speed based on an arrangement of the respective regions extracted by the region extracting apparatus. An endoscope inserting direction detecting apparatus includes a light receiving apparatus for receiving light from a visual field narrower than an ordinary observing field of the endoscope, a scanning apparatus for scanning the visual field of the light receiving apparatus and a judging apparatus for determining an endoscope inserting direction based on the received light amount by the light receiving apparatus in the respective visual field directions obtained by scanning the visual field of the light receiving apparatus by the scanning apparatus.

    摘要: An endoscope having a light source unit, a light guide fiber for guiding illumination light from the light source unit to the distal end in the inserting section of the endoscope main body, an optical system provided in the distal end for guiding the illumination light transmitted via the light guide fiber to an object, and a solid-state image pickup element incorporated in the distal end. A lens of the optical system is supported by a frame movable along an optical axis thereof. The frame is moved along the optical axis by a wire operating device provided in a control section of the endoscope main body in order to vary the angle of view of the optical system, i.e., the illuminating angle of the illuminating light. The image obtained by the solid-state image pickup element is enlarged by an image enlargement processor in accordance with the angle of view of the optical system, and is displayed. The image enlargement processor has a first frame memory and a second frame memory. The first frame memory receives only a predetermined horizontal scanning line components of the image which corresponds to the angle of view, and enlarges the image along the horizontal direction. The second frame memory receives only a predetermined component of each scanning line component read out from the first frame memory which corresponds to the angle of view, and enlarges the image along the vertical direction.

    摘要: An ultrasonic endoscope according to the present invention comprises an insertion portion having a hard distal end portion. A first holding member is provided to the hard distal end portion, and an ultrasonic vibrator is mounted on the first holding member. A second holding member, detachably mounted with respect to the first holding member, is provided at the hard distal end portion, and an observation optical system is mounted on the second holding member. The second holding member is fixed to the first holding member by a fixing means. In the ultrasonic endoscope with the above arrangement, the first holder for holding the ultrasonic vibrator can be separated from the second holder for holding the observation optical system.
