20100056865 | ACTUATOR FOR INTRADUCTAL MOVING BODY AND ENDOSCOPE - To bring a propulsion mechanism into reliable contact with a duct wall and transfer just a propulsion force to the duct wall without transferring an unnecessary retraction operation. An actuator for intraductal moving body includes: a propulsion mechanism which generates a drive force via a duct wall to generate a propulsion force for movement in a duct; a base mechanism which supports the propulsion mechanism and causes the propulsion mechanism to abut against and separate from the duct wall; and two or more pairs of bilayer mechanisms provided axially symmetrically. | 03-04-2010 |

20120035419 | ELECTRONIC ENDOSCOPE SYSTEM - An electronic endoscope system is composed of an electronic endoscope, a light source apparatus, and a temperature converter. The electronic endoscope has a CMOS sensor in a distal portion of an insert section to be inserted into a patient's body cavity. Illumination light from the light source apparatus is applied to the body cavity through the distal portion. The temperature converter obtains an average pixel value of an optical black (OB) region out of an imaging signal from the CMOS sensor, and converts the average OB pixel value into a temperature of the CMOS sensor on a frame-by-frame basis with the use of data in a temperature conversion table. The table represents a relationship between the average OB pixel value and the temperature of the CMOS sensor. Light quantity of the illumination light is adjusted in accordance with the temperature of the CMOS sensor to prevent deterioration of image quality. | 02-09-2012 |

20130211217 | ENDOSCOPE SYSTEM, PROCESSOR DEVICE THEREOF, AND IMAGE PRODUCING METHOD - First and second white light is generated by excitations of phosphors with first and second laser beams having center wavelengths of 473 nm and 445 nm, respectively. The first and second white light is applied, in respective frames, sequentially to a region of interest in a subject. A color image sensor images the region of interest in the each frame. Based on a shift amount, calculated from green signals of first and second frames, between images, an image of a blue signal of the first frame is moved to be aligned with an image of a green signal and an image of a red signal of the second frame. After the alignment, an oxygen saturation image representing an oxygen saturation level of hemoglobin in blood is produced from the blue signal of the first frame and green and red signals of the second frame, and displayed on a display. | 08-15-2013 |

A blood vessel enhanced image in which a superficial blood vessel and a middle to deep-layer blood vessel are enhanced is produced based on reflection images of the first and fourth narrow band light N1 and N4. An oxygen saturation image, which images an oxygen saturation level of hemoglobin in blood, is produced based on reflection images of the second to fourth narrow band light N2 to N4. The produced blood vessel enhanced image and the oxygen saturation image are displayed side by side on a monitor. | 04-10-2014 |
20140152790 | ENDOSCOPE SYSTEM AND OPERATING METHOD THEREOF - An observation object is imaged under irradiation with oxygen saturation level measurement light to obtain a first image signal, and the observation object is imaged under irradiation with white light to obtain a second image signal. A normal light image is produced from the second image signal. An oxygen saturation level is calculated from the first and second image signals. The calculated oxygen saturation level is imaged in an oxygen saturation image. By superimposing the normal light image on the oxygen saturation image, an emphasized oxygen saturation image is produced. In the emphasized oxygen saturation image, an abnormal area in which a calculation result of the oxygen saturation level is likely to be abnormal is emphasized by its brightness. The produced emphasized oxygen saturation image is displayed on a display device. | 06-05-2014 |
