The present invention has: a variation amount specifying means for specifying the amount of variation of the position of a subject relative to a sensing means during an interval from the timing at which preceding image data created immediately before target image data are created until the timing at which the target image data are created among a plurality of image data created on the basis of a result of sensing of radiation by the sensing means, the radiation having passed through the subject; a radiation amount setting means for setting the amount of radiation radiated by a radiating means, on the basis of the variation amount; a synthesis ratio determining means for determining a synthesis ratio on the basis of the variation amount; and a noise reducing means for reducing noise in the target image data by synthetizing image data created prior to the target image data with the target image data in accordance with the synthesis ratio. |
