| 20100317923 | ENDOSCOPE SYSTEM, ENDOSCOPE, AND DRIVING METHOD - An endoscope includes an elongated tube. An objective lens system is disposed in the elongated tube, for passing image light from an object. A fiber optic image guide includes plural optical fibers bundled together, has a distal tip, is inserted through the elongated tube, for transmitting the image light focused on the distal tip by the objective lens system in a proximal direction. A displacing device displaces the distal tip laterally and periodically upon receiving entry of the image light being focused by use of a piezoelectric actuator positioned outside the distal tip. An image sensor creates images in plural set positions of the distal tip. First to fourth images among the plural images created consecutively are combined to form a first synthesized image. Then second to fifth images among the plural images without use of the first image are combined to form a second synthesized image. | 12-16-2010 |
| 20110034770 | ENDOSCOPIC DEVICE - An endoscopic device comprises: an illuminating unit which emits illuminating light from an endoscope tip portion, and includes a plurality of kinds of light sources different from one another in an emission wavelength; an imaging unit which obtains a pickup image of a region to be observed of a subject radiated with the illuminating light; and the color tone controlling unit which changes a color tone of the illuminating light by changing an output light quantity ratio among the plurality of kinds of light sources. | 02-10-2011 |
| 20110069164 | ENDOSCOPE SYSTEM - An endoscope system includes an endoscope and a control device. The endoscope includes an illumination optical system with a fluorescent body formed in an optical path and an imaging optical system with an imaging element outputting an imaging signal of an optical image. The control device includes a light source unit which supplies an excitation light to the illumination optical system so as to emit light from the fluorescent body and an image processing section which corrects the imaging signal output from the imaging element. The image processing section includes: an illumination light spectrum calculating unit, a chromaticity correction table creating unit and an image correcting unit. | 03-24-2011 |

| 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 |
