A radiographic imaging apparatus includes: an effective pixel area including a plurality of detection areas, in each of which a first pixel including a photoelectric conversion element and a second pixel including a light-blocking element are provided; a plurality of signal processing units that are provided so as to correspond to the plurality of detection areas and each process, for a corresponding one of the detection areas, an output signal from the first pixel and an output signal from the second pixel provided in the corresponding one of the detection areas; and a correction unit that makes, for each signal processing unit among the plurality of signal processing units, a correction to the output signal from the first pixel processed by the signal processing unit, by using the output signal from the second pixel processed by the signal processing unit.
