Abstract

A radiation imaging apparatus is provided. The apparatus comprises pixels that configure a plurality of rows and a plurality of columns and are configured to obtain a radiation image, and a readout unit configured to readout signals from the pixels. The readout unit reads out a signal from pixels simultaneously selected, out of the pixels, in accordance with a row selection line connected in common for each row. In a case where a first pixel for detecting an incident dose during capturing of a radiation image that is set from the pixels is a defective pixel, the readout unit reads out a signal for detecting an incident dose from a second pixel selected from the pixels so that at least one row is arranged between the row that includes the first pixel and a row that includes the second pixel.
