Abstract

A control deviceincludes an image acquisition unitconfigured to acquire a radiographic image obtained by irradiating a subject F with radiation and capturing an image of the radiation passing through the subject F, a noise map generation unitconfigured to derive an evaluation value obtained by evaluating spread of a noise value from a pixel value of each pixel in the radiographic image on the basis of relationship data indicating a relationship between the pixel value and the evaluation value and generate a noise map that is data in which the derived evaluation value is associated with each pixel in the radiographic image, and a processing unitconfigured to input the radiographic image and the noise map to a trained modelconstructed in advance through machine learning and execute image processing of removing noise from the radiographic image.
