Abstract: An examination device includes a processor, and the processor detects, in swallowing videoendoscopy in which an inflow object is given to a subject and a swallowing action is observed, at least two timings among a swallowing instruction timing at which a swallowing instruction is given, an inflow timing of the inflow object into the pharynx during the swallowing action, and a swallowing reflex triggering timing in the subject.

Abstract: An endoscope system includes an endoscope, a video processor, a power source unit, and a parameter control device. The endoscope includes an image pickup unit and an illumination unit. The power source unit supplies electric power to the image pickup unit and the illumination unit. The video processor includes an image processing unit configured to generate an endoscope image. The parameter control device includes a data collection unit, a determination unit, and a parameter determination unit. When the data collection unit acquires one or more pieces of start information during execution of electric power consumption reducing processing, the determination unit determines to stop the electric power consumption reducing processing and execute high image quality achieving processing.

Abstract: An endoscope system includes an endoscope, a video processor, and a parameter control device. The parameter control device causes the endoscope and the video processor to execute predetermined processing by controlling a plurality of parameters used in the endoscope and the video processor. The parameter control device includes a data collection unit, a determination unit, and a parameter determination unit. The determination unit determines contents of constraint processing by determining a plurality of pieces of information acquired by the data collection unit, and determines contents of recovery processing so that a function for displaying an endoscope image is recovered, the function being degraded through the constraint processing. The parameter determination unit determines one or more parameters used in the constraint processing and one or more parameters used in the recovery processing.

Abstract: An endoscope system includes an endoscope, a video processor, and a parameter control device. The parameter control device causes the endoscope and the video processor to execute predetermined processing by controlling a plurality of parameters used by the endoscope and the video processor. The parameter control device includes a data collection unit, an operation mode determination unit, and a parameter determination unit. The operation mode determination unit selects one or more operation modes from among an electric power consumption reducing mode, a wireless transmission amount reducing mode, a high image quality achieving mode, and a standard mode by determining the plurality of pieces of information acquired by the data collection unit. The parameter determination unit determines the plurality of parameters based on one or more operation modes selected by an operation mode selection unit.

Abstract: An endoscope includes an insertion portion having a light source portion configured to emit illuminating light therefrom when inserted into a body cavity. An imaging portion is configured to capture an image in the body cavity. A transmission portion configured to transmit the image captured by the imaging portion. A battery is configured to supply electric power needed for endoscopic observation. A power control portion is configured to selectively control a supply of electric power to all of the light source portion, the imaging portion, and the transmission portion in a standby mode in which power consumption is reduced compared with a normal operation mode in which a supply of electric power is performed from the battery to all of the light source portion, the imaging portion, and the transmission portion.
