Abstract: Detections in video frames of a video signal, which are output from a machine learning model, are associated to generate a detection chain. Display of a detection in the video signal is caused based on a position of the detection in the detection chain, the confidence value of the detection and the location of the detection.

Abstract: A device, system, and method that: acquires information that a sterilized endoscope, having reusable and non-reusable parts, is used; outputs an instruction for collecting the used endoscope from a medical institution; acquires information on the number of endoscopes scheduled for inspection, a predetermined number of endoscopes not scheduled for inspection, and the number of endoscopes in an endoscope inventory; outputs an instruction for delivering a non-used replaceable endoscope to the institution in response to the collection instruction; and outputs an instruction for delivering a non-used endoscope to the institution when equation (2) is not satisfied, equation (2) being: endoscope inventory quantity>number of endoscopes scheduled for inspection+predetermined number.

Abstract: An endoscope includes: an image sensor in which a color filters having two or more colors is disposed at an imaging position and has a predetermined array pattern; and a correction processing unit configured to repeatedly perform processing of changing a target pixel value at a target imaging position to a median value between a neighboring pixel value and the target pixel value, while changing the target imaging position, when a pixel value at a neighboring imaging position near the target imaging position including at least two most neighboring imaging positions on a row closest to the target imaging position with the target imaging position interposed therebetween at an imaging position of a color filter, which is on a row along one direction identical to the target imaging position in image data output from the image sensor, and has a same color as a color filter at the target imaging position, is set as a neighboring pixel value.

Abstract: Provided are an intraocular lens and a technique associated therewith, wherein an average value (exceeding 0 D) of base difference values within a first region from a lens center O to a position r1 of a first boundary is greater than 5 times an average value (exceeding 0 D) of base difference values within the first region from a lens center O of a virtual spherical lens having a base power at the lens center O to the position r1, a second region has a power resulting from adding one or more positive constant powers to a reference aspheric power, in a third region, the power is reduced so as to provide a negative longitudinal spherical aberration that cancels at least part of a positive longitudinal spherical aberration caused by a cornea, and a second step value is greater than a first step value.
