Patent ID: 8841628

Claim:
A radiographic image capturing apparatus comprising: an image capturing panel containing a plurality of pixels arranged in a matrix for converting a radiation, which is emitted from a radiation source and transmitted through a subject, into electric signals and storing the electric signals, a first readout control part for executing a first readout mode for reading one-frame image data by reading the electric signals stored in the pixels in a plurality of rows simultaneously, and an irradiation start judgment part for judging start of emission of the radiation from the radiation source to the image capturing panel, the emission of the radiation being judged to be started in a case where a value of the electric signals read by the first readout control part becomes larger than an arbitrarily settable threshold value, wherein the first readout control part executes the first readout mode until the emission of the radiation is judged to be started by the irradiation start judgment part, and in a case where the emission of the radiation is judged to be started by the irradiation start judgment part, the first readout control part acts to stop the reading of the electric signals and to switch the plurality of pixels of the image capturing panel to an exposure state.
