To provide a technique of informing an operator that a designated image area is not effective by preventing an image area segmented from a photographed image by an operator from being processed remaining ineffective.
At a step S104, when the operator presses an exposure switch, X-ray photographing is carried out. At a step S105, an irradiation field is recognized. At a step S106, density is adjusted by catching the feature of an image in the irradiation field. At a step S107, the image whose density is adjusted is displayed on a display part. At a step S108, when the operator instructs segmentation, this processing is advanced to a step S109 to investigate the image size of an instructed segmentation area. the feature of the image is simultaneously extracted. That is, it is investigated in this execution style that the image of the segmentation area has a feature attached to the photographing method button of "finger". Continually, when the area segmented at the step S110 is judged to be effective, the processing is advanced to a step S115. When the area segmented at the step S110 is judged to be ineffective the processing is advaned to a step S111, informing processing is carried out.
