<p>A radiographic imaging device comprising a radiation sensor in which multiple pixels are arranged in rows and columns and which obtains a radiographic image by detecting radiation with each pixel, a drive unit which causes the multiple pixels to be in a read state in units of lines of either the row or column and performs a detection drive for removing electrical charge accumulated in the radiation sensor, and a detection circuit which detects exposure of the radiation sensor to radiation on the basis of an electrical signal output from the radiation sensor due to the detection drive, wherein the radiographic imaging device has a setting unit for setting imaging modes thereof, and wherein when the imaging mode of the radiographic imaging device is in a first imaging mode for imaging a subject, the drive unit causes the pixels on each line to be in a first time read state by the drive to remove the electrical charge, and when the imaging mode is in a second imaging mode for obtaining a correction image without the subject, the drive unit causes the pixels on each line to be in a second time read state which is longer than the first time by the drive to remove the electrical charge.</p> |
