摘要： A processor for an endoscope according to an aspect is characterized by including: a controller executing program code to perform: acquiring, by the controller, an endoscopic image captured using first system information; calculating, by the controller, parameter on the basis of the endoscopic image acquired by the controller; discriminating a part of a subject using a first learning model that outputs a discrimination result of discriminating the part of the subject in a case in which the calculated parameter is input; outputting second system information using a second learning model that outputs the second system information in a case in which the parameter and the discriminated part of the subject are input; and determining, by the controller, a difference between the second system information output by the second learning model and the first system information.

摘要： 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.

摘要： A processor for an endoscope according to an aspect is characterized by including: a controller executing program code to perform: acquiring, by the controller, an endoscopic image captured using first system information; discriminating a part of a subject using a first learning model that outputs a discrimination result of discriminating the part of the subject in a case in which the acquired endoscopic image is input; acquiring, by the controller, a setting image associated with the discrimination result output by the first learning model; and outputting second system information using a second learning model that outputs the second system information in a case in which the acquired setting image and the part of the subject are input.
