Abstract
A radiation imaging apparatus includes a pixel array in which a plurality of pixels are arrayed and a processing unit configured to process pixel signals non-destructively read out from the respective pixels. The processing unit performs a first process of obtaining image data of a plurality of frames by repeatedly reading out image data while the pixel array is irradiated with radiation, with a group of pixel signals from the plurality of pixels corresponding to image data of one frame, and a second process of generating data for a radiation image based on data differences between the image data of the plurality of frames.
