1. An X-ray radioscopy device comprising: an image capturing unit configured to capture images of an object that has been irradiated by X-rays, and generate multiple frames of image data; an analysis processing unit configured to perform different analysis processes in parallel on the image data in order to extract a plurality of specific regions of the object in the image data, wherein a first process of the analysis processes is faster than a second process of the analysis processes; a detection unit configured to detect a movement of the object in the multiple frames; and a selection unit configured to select a region from one of a specific region extracted in the first process and a specific region extracted in the second process based on the detected movement.
