Patent number: 7658710Abstract: An endoscope system includes a light source for supplying three narrow wavelength bands including one wavelength band for exciting fluorescence, an excitation light cut filter for transmitting light having a wavelength greater than either 470 nm or 490 nm, and an image capturing unit for capturing the light transmitted by the excitation light cut filter and outputting three wavelength band signals corresponding to the three narrow wavelength bands of the light source. Also included are first, second and third frame memories for inputting and storing the three wavelength band signals, respectively, and first, second and third output ends for outputting first, second and third color signals, respectively, to a monitor for displaying an image. An image processor receives signals from the first, second and third frame memories respectively and selects among the first output end, the second output end and third output end for outputting the received signals to the monitor.Type: GrantFiled: December 18, 2006Date of Patent: February 9, 2010Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana, Kazuhiro Gono

Patent number: 7367537Abstract: In a color-image pickup device, light is decomposed by R filters, G filters, B filters, and an infrared blocking film into R, G, and B components, and photoelectric conversion elements arranged in a light-reception area receive the R, G, and B components, and output R, G, and B picture signals. The relative reduction in the intensity of the R picture signal, which increases with the incident angle of the R component, is compensated for by relatively increasing the transmittance of the R component or the gain of the R picture signal, or setting light-reception efficiencies at the respective photoelectric conversion elements so as to relatively increase the light-reception efficiency of the R component, with an increase in the distance from the center of the light-reception area.Type: GrantFiled: March 24, 2004Date of Patent: May 6, 2008Assignee: FUJIFILM CorporationInventor: Hiroshi Ibe

Patent number: 7226412Abstract: An endoscope system in accordance with an embodiment of the present invention includes an endoscope with a monochrome image pickup device for capturing reflected light and fluorescence from the body cavity, an excitation light cut filter which is installed in front of the image pickup device for shielding excitation light, and an endoscope ID which includes information on the type of the endoscope. A light source unit includes a first switching filter that irradiates light including excitation light for a fluorescent image mode and a filter for generating continuous light for a normal-light image mode. The filters switch based between the fluorescent image mode and the normal-light image mode. A second switching filter with a limiting filter that limits certain wavelengths of excitation light of the first switching filter is provided. The limiting filters are switched according to the endoscope ID or observation state in the fluorescence mode.Type: GrantFiled: May 25, 2004Date of Patent: June 5, 2007Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana, Kazuhiro Gono

Patent number: 7215886Abstract: The present invention is related to an optical communication module for transmitting high frequency signals (e.g., 10 Gbit/s and higher data rates) between an optical element and an external circuit. In an illustrative embodiment, the optical communication module includes signal transmission lines and ground lines formed on a ceramic substrate, a flexible wiring board, and a printed circuit board. The widths of the signal lines and the ground lines vary, as well as the spacing between the signal and ground lines. This facilitates characteristic impedance matching among the signal lines to within about 50?.Type: GrantFiled: August 15, 2002Date of Patent: May 8, 2007Assignee: Hitachi, Ltd.Inventors: Shigenobu Maruyama, Kazumi Kawamoto, Hiroaki Furuichi, Tooru Yoshida, Isamu Yoshida, Katsuya Oono, Osamu Yamada, Hiroshi Ibe, Shigeru Tokita, Tarou Tonoduka, Yasunori Iwafuji, Katsumi Kuroguchi

Patent number: 6960165Abstract: In a light source unit, a switchable filter section in which an RGB filter and a fluorescence observation filter can be shifted into the light path is disposed in front of a lamp. When fluorescence image mode is selected, excitation light in a part of the wavelength band of the blue wavelength band is supplied to an electronic endoscope, and the excitation light which is reflected by the subject is shielded by an excitation light shielding filter situated in front of a CCD, whereby a fluorescence image can be obtained. On the other hand, if normal-light image mode is selected, then R, G, B light is supplied sequentially, and even under illumination of B light, the color component image in the wavelength bands which are not shielded by the excitation light shielding filter are captured, thereby yielding a normal-light image also, and hence making it possible to capture both a fluorescence image and a normal-light image by means of a single image pickup element.Type: GrantFiled: May 14, 2002Date of Patent: November 1, 2005Assignee: Olympus CorporationInventors: Hitoshi Ueno, Takeshi Ozawa, Kazunari Nakamura, Isami Hirao, Hiroshi Ibe, Koichi Yoshimitsu, Yuichi Morizane, Mamoru Kaneko, Shunya Akimoto, Masaki Terakubo, Katsuichi Imaizumi, Nobuyuki Doguchi, Sakae Takehana
