An approximate subject region is acquired by eliminating a non-X-ray irradiated region and a direct irradiated region from an X-ray image, an initial region in the approximate subject region is decided by analyzing the approximate subject region. The initial region is enlarged by using region growing processing, and thereby a subject region is acquired. Then, acquired is a subject region image which corresponds to the subject region in the X-ray image, which was acquired by enlarging the initial region. |
