PROBLEM TO BE SOLVED: To appropriately perform shading correction when photographing radiation images using a radiation detector. SOLUTION: A shading correction data acquisition part 42 acquires first shading correction data H1 due to a radiation source 14 and second shading correction data H2A, H2B due to FPDs 22A, 22B of cassettes 20A, 20B beforehand, and stores them in a storage part 38. When performing photographing using the cassette 20A for instance, a detection part 40 detects the direction of the FPD 22A, and on the basis of it, an image processing part 34 rotates the first shading correction data H1 relative to the second shading correction data and generates final shading correction data H0. Then, the shading correction of radiation image data acquired by photographing is performed by the final shading correction data H0. COPYRIGHT: (C)2011,JPO&INPIT |
