1. A radiation imaging apparatus, comprising:
a plurality of pixels configured to acquire a radiation image; and
a readout circuit configured to read out a plurality of signals from the plurality of pixels, wherein
correction image data used for performing offset correction is acquired from the plurality of pixels in an acquisition mode, which is defined by an estimated value based on at least one of the plurality of signals output from the plurality of pixels based on an imaging mode set by a user, and system noise to be generated when the readout circuit reads out the plurality of signals.
