A radiographic imaging control apparatus includes a control unit, a setting unit, and an obtaining unit. The control unit performs a first control to cause a radiation sensor to transit into a state where electric charges can be stored if it is determined that a predetermined standby time elapses and performs a second control to cause the radiation sensor to transit into the state where electric charges can be stored in response to a signal received from a detection unit configured to detect start of a generation of radioactive rays. The setting unit designates either the first control or the second control as a control to be performed. The obtaining unit acquires radiation image data from the radiation sensor.

A radiography apparatus is provided in which delays in it do not occur due to the influence of preliminary preparation of a radiation detector. The FPD 4 receives a signal from an X-ray tube control unit 6 and then completes preliminary preparation for the detection of radiation during accelerated movement of an X-ray tube 3 or the FPD 4. That is, the accelerated movement of the X-ray tube 3 or the FPD 4 and the preliminary preparation for the detection of radiation are carried out simultaneously. This enables imaging to be started immediately after the start of constant speed movement of the X-ray tube 3 or the FPD 4 without having to wait for constant speed movement thereof to start preliminary preparation of the FPD 4 as in conventional apparatuses. As a result, delays in imaging do not affect the radiation image.
