Abstract
When an operator presses an exposure switch in step S, X-ray imaging is executed. Radiation field recognition is performed in step S. In step S, density adjustment is performed by obtaining characteristic features of an image in the radiation field. The density-adjusted image is displayed on a display unit in step S. If the operator gives a crop instruction in step S, the flow advances to step Sto check the image size of the designated and extracted region. At the same time, characteristic features are extracted from the image. That is, in the embodiments, it is checked whether an image in an extracted region has characteristic features attached an imaging method button for 'finger'. If it is determined in step Sthat the extracted region is valid, the flow advances to step S. If it is determined that the region is invalid, the flow advances to step Sto execute notification processing.
