<P>PROBLEM TO BE SOLVED: To provide a radiographic imaging device, a radiographic imaging system, the control program for the radiographic imaging device, and the control method for the radiographic imaging device which can detect the irradiation start of radiation with accuracy even when a noise is generated due to a disturbance element and so on. <P>SOLUTION: When radiation is irradiated, an electric signal (electric charge information) output from a picture element 20B for radiation detection during the charge accumulation of an electric charge generated according to relevant radiation is detected by a signal detection circuit 105 during a predetermined detection period. A control part 106 determines whether the time change of the electric signal (electric charge information) has a characteristic which is established preliminarily as a noise. When determining that it does not, because the irradiation start of radiation is detected appropriately, without any change the charge accumulation period is continued and a radiographic image is photographed. On the other hand, when determining that it does, that is, it is a noise, it is regarded as the wrong detection of the irradiation start of radiation. The charge accumulation period is discontinued (evacuated) and is transited to a radiation detection period. <P>COPYRIGHT: (C)2013,JPO&INPIT |
