Title: Blackening processing method and apparatus for radiation images

Abstract: A radiation image is partitioned into a plurality of subregions. A certain subregion, which is among the plurality of the subregions, is set as a blackening region, which is to be subjected to a blackening process, or as a non-blackening region, which is not to be subjected to the blackening process. Subregions, which are adjacent to each other among the plurality of the subregions, are set alternately as a blackening region and a non-blackening region by taking the certain subregion as a reference subregion. The blackening process is performed on the subregion, which has thus been set as the blackening region.
