Claim:
1. An X-ray imaging apparatus comprising: a sensor array configured to obtain X-ray image data; a read-out circuit configured to read out electric signals from the sensor array to obtain X-ray image data; a determination unit configured to determine stability of offset data included in the X-ray image data obtained by the read-out circuit before the X-ray image data is obtained based on data that the read-out circuit has repeatedly read out during a period in which a condition where no X-ray is irradiated continues before an irradiation of the X-ray; and a control unit configured to, when it is determined that the offset date is stable, perform a first control in which offset data for offset correction to X-ray image data is obtained using the read-out circuit before obtaining the X-ray image data, and perform a second control after the first control, in which X-ray image data is obtained using the read-out circuit.
