Publication number: 20210076903Abstract: An endoscope system includes an endoscope including at least one switch, each of which can be assigned two functions, and a controller. The controller sets a plurality of function pairs, each of which is composed of a combination of any one of a plurality of first functions and any one of a plurality of second functions, and assigns one function pair selected from the plurality of function pairs to the switch, measures a switch pressing time period after the switch is pressed, and executes the first function when the switch pressing is released before a predetermined first time period elapses after the switch is pressed and executes the second function when the switch pressing time period passes the first time period.Type: ApplicationFiled: November 27, 2020Publication date: March 18, 2021Applicant: OLYMPUS CORPORATIONInventors: Takeshi URASAKI, Koichi NIIDA, Masaki KONDO, Takuya OGURA, Aki MATSUMOTO, Ryunosuke MATSUSHIGE, Satoru ONO, Takahiro YUMOTO, Hideyuki WADA, Sachiko HASHIMOTO, Tomomi OUCHI

Patent number: 8817077Abstract: An endoscope system includes processors, and settings in the processors are at least partially in common. And a setting content in a processor determined to have a higher priority is transmitted to a processor determined to have a lower priority, based on a predetermined operation, and the processor changes a setting content that is in common with a setting content in the processor among the received setting contents.Type: GrantFiled: May 3, 2013Date of Patent: August 26, 2014Assignee: Olympus Medical Systems Corp.Inventors: Takeshi Urasaki, Ryu Oshima, Hiroshi Tamai

Patent number: 8581970Abstract: A light source unit, which is connected to a control unit and an endoscope, radiates a pre-determined light quantity of white light based on a signal from the control unit. The light source unit includes a lamp as a white light source, an infrared cut filter, a light quantity limiting filter, being inserted/removed on an optical path, for limiting light quantity in a pre-determined wavelength region of white light, a filter insertion/removal driving unit for inserting/removing the light quantity limiting filter on an optical path, and a condensing lens for outputting white light. For example, when a transmission rate of a blue band is 100%, the light quantity limiting filter limits transmission rates of other bands to 50%. This improves S/N in discrete spectral image generation with illumination light in a visible light region.Type: GrantFiled: September 15, 2008Date of Patent: November 12, 2013Assignee: Olympus Medical Systems Corp.Inventors: Kenji Yamazaki, Kazuhiro Gono, Takeshi Urasaki, Takashi Takemura
