Zusammenfassung: | A radiation imaging apparatus includes an imaging unit having a plurality of pixels. Each of the plurality of pixels includes a conversion element configured to convert radiation into an electrical signal, a processing circuit configured to process the electrical signal output from the conversion element, and a holding unit configured to sample and hold the electrical signal output from the processing circuit. After radiation irradiation from a radiation source is started and before next radiation irradiation from the radiation source is started, the holding unit samples and holds, at a first timing and a second timing which is after the first timing, the electrical signal output from the processing circuit. A gain of the processing circuit at the first timing and the gain of the processing circuit at the second timing are different from each other. |
