    摘要： Adjustment processing including an adjustment level for suppressing occurrence of an artifact along a line corresponding to a scanning line of an image sensor in the frame image is performed when a biological tissue is imaged as a moving image by a rolling shutter method.
    An endoscope system includes: a light source device; an electronic endoscope including an image sensor that images a biological tissue by a rolling shutter method; and a processor including an adjustment unit that is a part adjusting luminance of the frame image by combining adjustment of an exposure time of the image sensor with at least one of adjustment of light intensity of the illumination light and gain adjustment for determining a signal level of the frame image obtained from the image sensor, the adjustment unit determining whether or not a motion amount of an object image in the captured image or information regarding a blurring amount satisfies an adjustment condition and performing the adjustment processing by adjusting an adjustment level representing a degree of strength of the adjustment processing by a magnitude of a value according to at least the determination result.

    摘要： The present invention relates to a multispectrum endoscope and an endoscope system comprising same. The multispectrum endoscope of the present invention comprises: a first light source emitting infrared rays having a plurality of wavelengths; a plurality of multimode optical fibers for guiding the infrared rays emitted from the first light source toward a sample; a second light source emitting a visible ray; an optical fiber for guiding the visible ray emitted from the second light source toward the sample; a lens part for receiving a fluorescent signal emitted from the sample and a visible light signal reflected off the sample; and an optical fiber bundle for guiding the fluorescent signal and/or the visible light signal received by the lens part toward a multispectrum photodetector, wherein the optical fiber bundle is disposed so as to be surrounded by the plurality of multimode optical fibers, and the end portion of the multispectrum endoscope emitting the visible ray surrounds at least a portion of the plurality of multimode optical fibers.
