1. A radiographic imaging apparatus comprising:
a plurality of pixels disposed to form a plurality of rows and a plurality of columns;
a drive circuit configured to control the plurality of pixels through a plurality of drive lines extending in a row direction; and
a detection unit configured to detect a start of radiation irradiation, wherein,
the drive circuit comprises a shift circuit configured to perform a shift operation of changing the drive line to be activated, among the plurality of drive lines, in response to a shift control signal input to the drive circuit, and
the drive circuit has a mode of activating a second drive line among the plurality of drive lines in response to the shift control signal input for a second time after a first drive line among the plurality of drive lines is activated during a period up to when the detection unit detects the start of radiation irradiation, at least two drive lines of the plurality of drive lines being disposed between the first drive line and the second drive line.
