An average offset image is acquired without irradiation of a radiation. A first image is acquired when a first time elapses from continuous irradiation with the radiation for imaging a subject on a pixel region. A second image is acquired when a second time longer than the first time elapses from an end of the continuous irradiation. The irradiation with the radiation for imaging the subject is performed on the pixel region after an elapse of the second time from the end of the continuous irradiation and a pixel signal from the pixel region is read out to acquire a radiographic image. An offset image representing an offset component and an afterimage representing an afterimage component according to a time of the continuous irradiation, the first time, the second time, and a defined time are generated based on the first image, the second image, and the average offset image.
