<p>A radiation imaging device stores an offset image and a gain correction image corresponding to a plurality of accumulation times before imaging, acquires a lag image based on the stored images, and acquires a radiation image. The radiation imaging device removes a lag from the radiation image by using a lag image so as to perform lag correction. Thus, by removing a lag from an offset image corresponding to the accumulation time and a radiation image considering a gain correction image by using the offset image corresponding to the accumulation time and the lag image considering the gain correction image, it is possible to easily remove a time delay containing an offset and a gain component included in the radiation detection signal from the radiation detection signal.</p> |
