There is provided a technology that enables an operator to designate whether or not to continue imaging if divided capture has been interrupted in a radiographic apparatus. During continuation of divided capture, the state of an irradiation switch for designating irradiation of radiation is detected by an irradiation switch state detection unit. When a suspension of the designation of irradiation of radiation has been detected, information indicating continuation of imaging, performing of imaging again, or cancellation of imaging is presented to an operator, thereby preventing an unintended interruption of imaging.
