Patent ID: 8605856

Claim:
A radiation image capturing device comprising: a plurality of pixels that are each provided with a sensor portion, that generates a charge in accordance with an amount of radiation irradiated thereon and accumulates the generated charge, and with a switching element that reads out the charge generated and accumulated at the sensor portion and outputs the charge to a signal line; a detection unit that detects a start of irradiation in a case in which electronic signals corresponding to the charges generated at the sensor portions satisfy a pre-specified condition for irradiation detection; and a control unit that, after the start of irradiation of radiation is detected by the detection unit, acquires electronic signals corresponding to the charges read out from the pixels for each of pre-specified regions, determines whether the acquired electronic signals include an electronic signal caused by noise for each of the pre-specified regions, and, in a case in which an electronic signal caused by noise is included, performs control that includes associating a radiation image with information relating to a pre-specified region in which it is determined that an electronic signal caused by noise is included, and storing thereof at at least one of within or outside the radiation image capturing device.
