1. A radiation detection device comprising:
a pixel region in which a plurality of pixels for detecting a radiation are arranged;
a readout unit that reads out a pixel signal from the pixel region; and
at least one processor,
wherein the processor is configured to:
average a plurality of images acquired by reading out a pixel signal from the pixel region a plurality of times in a state where irradiation with the radiation is not performed to acquire an average offset image;
perform continuous irradiation with the radiation for imaging a subject on the pixel region and read out the pixel signal from the pixel region when a first time elapses from an end of the continuous irradiation to acquire a first image;
read out the pixel signal from the pixel region when a second time longer than the first time elapses from the end of the continuous irradiation to acquire a second image;
perform irradiation with the radiation for imaging the subject on the pixel region after an elapse of a defined time from the end of the continuous irradiation and read out the pixel signal from the pixel region to acquire a radiographic image; and
generate an offset image representing an offset component and an afterimage image representing an afterimage component according to a time of the continuous irradiation, the first time, the second time, and the defined time, based on the first image, the second image, and the average offset image.
