Patent number: 7221388Abstract: This invention relates to an endoscope image sensing apparatus which can switch suitable color matrixes in accordance with the type of observation region, the type of light source used, or the like, and obtain good color reproduction corresponding to the type of observation region or the type of light source used. This apparatus uses a one-chip color CCD as an image sensing means. A CPU reads out corresponding color matrix coefficients from a ROM, and outputs the coefficients to a color separation circuit. The color separation circuit executes a matrix computation based on the color matrix to convert luminance and color difference signals into primary color signals.Type: GrantFiled: November 9, 2004Date of Patent: May 22, 2007Assignee: Olympus Optical Co., Ltd.Inventors: Masaru Sudo, Kanichi Matsumoto

Patent number: 7063692Abstract: A plurality of handpieces used to perform an operation is connected to a main operation apparatus, which generates a driving signal, through connectors formed on the main apparatus. When an operator holds a handpiece he/she wants to use, an output line over which the driving signal is transmitted is routed to the held handpiece owing to an output of a sensor that detects a change in capacitance stemming from the hold. The operator therefore need not manually set a mode in which the driving signal is applied to the handpiece he/she wants to use. Moreover, a port number assigned to a port to which the output line is routed is indicated on a display device. The operator can readily identify the usable handpiece.Type: GrantFiled: July 28, 2003Date of Patent: June 20, 2006Assignee: Olympus CorporationInventors: Tomohisa Sakurai, Hiroyuki Takahashi, Masaru Sudo, Takeaki Nakamura, Keiji Shioda, Takashi Ozaki, Makoto Miyawaki

Publication number: 20030187349Abstract: A sentinel lymph node detecting system comprises an inserting portion with a small diameter which can be inserted into the body cavity, an X-ray detecting unit for two-dimensionally detecting X-rays, and an optical imaging unit 3 for taking visible-light images, which are mounted to the tip of the inserting portion. The X-ray detecting unit and the optical imaging unit are disposed along the longitudinal direction of the inserting portion, and are closely disposed one to another so as to observe in the same direction. A radioactive tracer accumulated in sentinel lymph nodes is detected by the X-ray detecting unit. The X-ray detected image is smaller in size than the image taken by the optical imaging unit. Thus, sentinel lymph nodes can be quickly identified in a sure manner, and further, the load placed on a patient, such as the need to perform laparotomy, can be reduced.Type: ApplicationFiled: March 25, 2003Publication date: October 2, 2003Applicant: OLYMPUS OPTICAL CO., LTD.Inventors: Mamoru Kaneko, Toshihiro Shizuka, Tadahiro Nakano, Masaru Sudo, Hisao Yabe, Hitoshi Ueno
