Patent number: 11503990Abstract: An imaging system includes: a light source configured to emit illumination light; an imager configured to store an electric charge corresponding to an amount of received light and read out the stored electric charge as a signal value by using a rolling shutter method; a frequency detector configured to detect a vibrational frequency of a predetermined site of a subject; and an illumination controller configured to control emission of the illumination light during a readout period of the signal value. The illumination controller is configured to set a phase for an emission timing of the illumination light in an exposure period during which the imager stores the electric charge to be an identical phase at the frequency in each frame, and refer to respective phases set in exposure periods of chronologically adjacent frames to set an emission timing of the illumination light in the readout period.Type: GrantFiled: July 20, 2020Date of Patent: November 22, 2022Assignee: OLYMPUS CORPORATIONInventors: Manabu Ishizeki, Ryohei Kagawa

Patent number: 8988515Abstract: An endoscope system has an image pickup section and a processor. The image pickup section has a control register section which controls a sensor section, a nonvolatile memory which stores first setup data, a control signal interface section which sets the first setup data in the control register section, and an initialization check register which senses an abnormality in the control register section. When an abnormality is sensed, the control signal interface section reads out the setup data from the nonvolatile memory and performs control so as to reset the setup data in the control register section. The control signal interface section further has a memory which stores reset occurrence information upon occurrence of reset. The processor includes a control section which reads out the reset occurrence information from the memory, and, when reset is detected, transmits second setup information held by the processor to the image pickup section.Type: GrantFiled: January 7, 2013Date of Patent: March 24, 2015Assignee: Olympus Medical Systems Corp.Inventors: Hidetsugu Takahashi, Ryohei Kagawa, Manabu Ishizeki, Hidenori Hashimoto
