摘要： In an electronic endoscope system, a scope has a solid-state image sensor provided at a distal end thereof to generate image-pixel signals. An image-signal processing unit produces a video signal based on the image-pixel signals. An alteration system alters a peak-to-peak level of a synchronizing-signal component of the video signal. An manual setting system operates the alteration system to perform the alteration of the level of the synchronizing-signal component. An indicator system indicates the degree of alteration to the level of the synchronizing-signal component during the operation of the manual setting system.

摘要： 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.

摘要： A scanning endoscope processor, comprising a photoelectric converter and a controller, is provided. The scanning endoscope processor controls a scanning endoscope having first and second transmitters and an actuator. The photoelectric converter receives light transmitted from the second transmitter and generates a pixel signal according to the amount of light received. The second transmitter transmits reflected light and/or fluorescence from a point within an observation area illuminated by the light emitted from a first emission end. The first transmitter emits the light as a beam from the first emission end. The actuator moves the first emission end along a spiral course. The controller adjusts at least one of a first angular velocity and a generation cycle so that the product of the first angular velocity, the generation cycle, and a first distance is within a predetermined range.

摘要： 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.

摘要： A light transmitting part is formed on a second rotary shutter to intermittently transmit excitation light emitted from an excitation light source, which has a circumferential length substantially equal to a half of the entire periphery of the second rotary shutter in order to extend the period during which excitation light is emitted through a light distribution lens. As a living tissue is irradiated with excitation light, it generates autofluorescence. Although the autofluorescence is weak, a CCD can convert the image of the object under examination formed from the autofluorescence into a fluorescence video signal of a sufficient intensity level because excitation light is irradiated for an extended period of time. The obtained fluorescence video signal does not need to be amplified to an undesirable extent and hence can be processed with a high S/N to provide an appropriate diagnostic video signal that is free from noise.
