Abstract
A radiation imaging system for performing a plurality of times of radiation imaging is provided. A readout circuit generates a value corresponding to a signal read out from each pixel. A control unit causes the readout circuit to generate a first pixel value corresponding to a signal read out from each pixel, and a first offset value of the readout circuit before starting the plurality of times of radiation imaging. The control unit causes the readout circuit to generate a second pixel value corresponding to a signal read out from each pixel, and a second offset value of the readout circuit during a plurality of times of radiation imaging. A correction unit corrects the second pixel value by using the first pixel value, the first offset value, and the second offset value.
