Abstract

The radiographic image detection device performs: a radiographic image generation process of reading a pixel signal from a pixel region in a state in which radiation is emitted to generate a radiographic image; a first correction image acquisition process of reading the pixel signal from the pixel region a plurality of times to acquire a plurality of first correction images in a shorter accumulation time than the radiographic image or using binning reading in a state in which the radiation is not emitted immediately before radiography including the radiographic image generation process; a selection process of selecting, as an averaging target, at least two or more of the plurality of first correction images according to a time elapsed since immediately preceding radiography or an amount of variation in a residual image based on the first correction image; and a correction process of correcting the radiographic image on the basis of an average image obtained by averaging the first correction images selected as the averaging target.
