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.
Claims6
A blackening processing method for a radiation image, in which a blackening process is performed on a predetermined subregion in a radiation image, the method comprising the steps of:
- i) partitioning the radiation image into a plurality of subregions,
- ii) setting a certain subregion, which is among the plurality of the subregions, as a blackening region, which is to be subjected to the blackening process, or as anon-blackening region, which is not to be subjected to the blackening process,
- iii) setting subregions, which are adjacent to each other among the plurality of the subregions, alternately as a blackening region and a non-blackening region by taking the certain subregion as a reference subregion, and
- iv) performing the blackening process on the subregion, which has thus been set as the blackening region.
A blackening processing apparatus for a radiation image, in which a blackening process is performed on a predetermined subregion in a radiation image, the apparatus comprising:
- i) partitioning means for partitioning the radiation image into a plurality of subregions,
- ii) reference information setting means for setting reference information for setting a certain subregion, which is among the plurality of the subregions, as a blackening region, which is to be subjected to the blackening process, or as a non-blackening region, which is not to be subjected to the blackening process, and
- iii) blackening process means for:
- setting subregions, which are adjacent to each other among the plurality of the subregions, alternately as a blackening region and a non-blackening region by taking the certain subregion as a reference subregion, and
- performing the blackening process on the subregion, which has thus been set as the blackening region.
A blackening processing apparatus for a radiation image, in which a blackening process is performed on a predetermined subregion in a radiation image, the apparatus comprising:
- i) partitioning means for partitioning the radiation image into a plurality of subregions, and
- ii) blackening process means for:
- setting a subregion, which is closest to an image end among the plurality of the subregions, as a blackening region,
- setting subregions, which are adjacent to each other among the plurality of the subregions, alternately as a blackening region and a non-blackening region by taking the subregion, which is closest to the image end among the plurality of the subregions and has been set as the blackening region, as a reference subregion, and
- performing the blackening process on the subregion, which has thus been set as the blackening region.
