Claim Text:
1. A radiographic imaging device comprising: a plurality of pixels, each pixel including: radiation detection elements, that are pixels among the plurality of pixels, that have the switching elements short-circuited, and that output electric signals according to charges generated due to irradiated radiation; a detection section that detects the start of an irradiation of the radiation on the basis of the electric signals outputted from the radiation detection elements in a detection period; a control signal output section that outputs the control signals that control the read out of the charges; and a determination section that, in a radiographic imaging period after the detection section has detected the start of the irradiation of the radiation, detects the electric signals outputted from the radiation detection elements and, on the basis of a time variation of at least one of a polarity of the charges according to the detected electric signals or amplitudes of a waveform that expresses the time variation of amounts of the charges, determines whether or not the detection section has misdetected the start of the irradiation of radiation.
