20110074942 | ELECTRONIC ENDOSCOPE - An electronic endoscope includes an illumination unit, an imaging unit and an image generating unit. The illumination unit switches among plural light beams having different spectra so as to illuminate a subject. The light beams include white light and excitation light for exciting the subject to produce fluorescence. The imaging unit includes a solid-state imaging device, and an objective optical system. The objective optical system guides, to the solid-state imaging device, light returning from the subject which the illumination unit illuminates. The image generating unit generates image data based on image signals output from the imaging unit. The solid-state imaging device further includes a sensitivity adjusting unit that only lowers sensitivity, to the excitation light, of pixels which are sensitive to the fluorescence among a plurality of pixels of the solid-state imaging device. The light guided by the objective optical system is incident directly onto the solid-state imaging device. | 03-31-2011 |
20110118547 | ENDOSCOPE APPARATUS - An endoscope apparatus includes first and second light sources, an endoscope leading end portion, an irradiation window, an observation window, a light irradiation unit and an emission angle changing unit. The first light source outputs laser light for diagnosis. The second light source outputs laser light for therapy. The laser light for therapy is different in spectrum from the laser for diagnosis. The irradiation window and the observation window are provided in the endoscope leading end portion. The light irradiation unit emits the laser light for diagnosis and the laser light for therapy to the object through the irradiation window. The emission angle changing unit changes an emission angle at which the laser light for therapy is emitted through the irradiation window to be smaller than an emission angle at which the laser light for diagnosis is emitted. The object to be examined is observed through the observation window. | 05-19-2011 |
20110172492 | MEDICAL APPARATUS AND ENDOSCOPE APPARATUS - A medical apparatus includes a plurality of illumination windows which are disposed in a tip portion of an insertion unit to be inserted into a subject body and which emit light beams supplied from a plurality of light sources and having different spectra toward the subject body. The plurality of illumination windows include: a pair of first illumination windows; and a pair of second illumination windows which are disposed inside the pair of first illumination windows, respectively, and emit light beams having a shorter wavelength than light beams emitted from the pair of first illumination windows. The medical apparatus further includes an observation window through which to observe the subject body. | 07-14-2011 |
20110237894 | ENDOSCOPE APPARATUS - To provide an endoscope apparatus in which the observation image can be varied continuously as the observation magnification is varied by a zoom magnification varying manipulation so that an observation image suitable for an endoscope diagnosis is obtained at each observation magnification, and to thereby prevent the operator from feeling uncomfortable and increase the accuracy of a diagnosis. An endoscope apparatus is equipped with illuminating unit having plural light sources which generate light beams having different spectra, for illuminating an observation subject; imaging unit for imaging the observation subject; observation magnification varying unit for varying observation magnification of the imaging of the imaging unit; and light quantity ratio varying unit for continuously varying an emission light quantity ratio between the plural light sources according to the observation magnification that is set by the observation magnification varying unit. | 09-29-2011 |
20120010465 | ENDOSCOPE APPARATUS - A first irradiation portion that radiates white light onto a subject, a second irradiation portion that radiates narrow bandwidth light having a narrower wavelength bandwidth than the white light, and an observation window used to observe the subject are respectively disposed on a leading end surface of an endoscope insertion portion. Each of the first and second irradiation portions includes a pair of irradiation windows for emitting light therefrom. A straight line passing through a center point of the observation window and bisecting the leading end surface is defined as a boundary line. The pair of irradiation windows of the first irradiation portion are disposed on both sides of the boundary line. The pair of irradiation windows of the second irradiation portion are disposed on the both sides of the boundary line. Spectra of lights radiated from the irradiation windows of the second irradiation portion can be changed individually. | 01-12-2012 |
