Abstract
Provided is a technique to improve both the image quality of a radiation image and the operability of a radiation imaging apparatus. In the present invention, three or more unirradiated images are obtained before capturing a radiation image, and a temporal change in the amount of electric charges in each pixel is approximated using a non-linear function. At this time, the amount of residual electric charges is determined by evaluating a coefficient of determination of an approximate equation, and the most appropriate offset correction processing method is selected in accordance with the status of the determination.
