ABSTRACT:
A phase contrast image is generated on the basis of a plurality of radiation images of an object taken in imaging positions which are different from each other in the distance from the object. An enlargement/reduction processing is carried out on the radiation images as taken in the imaging positions according to the distances between the imaging positions so that the radiation images become substantially the same in their sizes, and a phase contrast image is generated on the basis of the radiation images thus processed.
