摘要

PROBLEM TO BE SOLVED: To solve the problem that it is difficult to calculate an incidence X-ray dosage because a gain value depending on the number of added pixels is not obtained due to non-linearity of analog calculation when adjacent pixel addition is performed on a FPD in an analog.

SOLUTION: A photographic device includes a detector including a plurality of detection elements that detect radiation intensity and performs analog addition of an analog electric signal according to distribution of the radiation intensity detected by the detector. The photographic device obtains correction information for correcting an electrical signal obtained by the analog addition indicating non-linear output for the number of added signals to be linear for the number of the added signals, and corrects the electrical signal obtained by the analog addition by the obtained correction information.
