Publication number: 20220335610Abstract: An image processing system includes a processor configured to acquire, as a processing target image, an in-vivo image, operate in accordance with a trained model, and output a recognition result representing a result of recognition of a region of interest in the processing target image. The trained model is trained by having undergone pre-training using a first image group including images captured in a first observation method, and having undergone, after the pre-training, fine-tuning that uses a second image group including images captured in a second observation method, as well as that uses ground truth regarding the region of interest included in the second image group. The first observation method is an observation method using normal light as illumination light, and the second observation method is an observation method using special light as the illumination light or an observation method in which a pigment has been dispersed onto the subject.Type: ApplicationFiled: July 5, 2022Publication date: October 20, 2022Applicant: OLYMPUS CORPORATIONInventor: Fumiyuki SHIRATANI

Patent number: 7580622Abstract: An imaging apparatus comprises an optical magnification changing mechanism which optically changes a magnification of an image, and an electronic magnification change mechanism which reduces or expands a magnification with respect to image data by signal processing. The optical magnification changing mechanism is configured so that a magnification is discrete and a focal position changes together with a focal distance. The electronic magnification change mechanism carries out an interpolation process such that the number of pixels is increased with respect to a predetermined region of read image data during an expanding process, and carried out a process for discretely sampling a wide region as compared with a readout region obtained by the sampling provided when no magnification conversion is made, during a reducing process, thereby offsetting a change of the focal position in the optical magnification changing mechanism.Type: GrantFiled: October 27, 2005Date of Patent: August 25, 2009Assignee: Olympus CorporationInventors: Nobuyuki Watanabe, Fumiyuki Shiratani, Noriyuki Iyama, Shinichi Mihara, Hiroyuki Minakata
