Abstract
While a solid-state detector is not being irradiated with a radiation, unexposed image data R0 are acquired from an exposure area of the solid-state detector and non-exposure image data r0are acquired from a non-exposure area, which is shielded by a shield plate against exposure to the radiation, of the solid-state detector. Then, while the solid-state detector is being irradiated with the radiation through a subject, exposed image data Rn are acquired from the exposure area, and non-exposure image data rn are acquired from the non-exposure area. The exposed image data Rn are corrected according to Rn-R0-(rn-r0) or Rn-R0.times.(rn/r0).
