Publication number: 20080143827Abstract: An endoscope apparatus to which an endoscope is detachably connected has an endoscope interface, an image processor and a parameter transfer control section. Here, the endoscope multiplexes a video signal obtained by an image pickup section with an endoscope ID as endoscope identification information, and transmits the signal to the endoscope apparatus. The endoscope interface separates the endoscope ID from the signal from the endoscope. The image processor has a parameter register in which a parameter related to an image process of the video signal is set, and a functional module for performing a predetermined image process with respect to the video signal based on the parameter. The parameter transfer control section reads the parameter corresponding to the endoscope ID separated in the endoscope interface, from a table memory for storing the parameter for each endoscope ID, and transfers the parameter to the parameter register.Type: ApplicationFiled: December 18, 2007Publication date: June 19, 2008Applicant: OLYMPUS CORPORATIONInventors: Naoyuki YOSHIZUMI, Kaoru KOTOUDA

Publication number: 20080132756Abstract: When a capsule is manufactured, a unique number such as a serial number is stored in non-volatile memory in the capsule. If the capsule is used with an external apparatus, the unique number is sent from the capsule to the external apparatus. The external apparatus relates each unique number with a capsule ID comprising a small number of bits in a management table formed in non-volatile memory and sends the capsule ID to the capsule, and the capsule ID with the small number of bits is set as an identifier in the capsule. In this manner, it is made unnecessary to provide a switch in the capsule for setting the identifier and it becomes possible to reduce and send the quantity of information sent as the identifier.Type: ApplicationFiled: February 6, 2008Publication date: June 5, 2008Applicant: OLYMPUS CORPORATIONInventors: Manabu Fujita, Masatoshi Homan, Motoo Azuma, Kaoru Kotouda
