Abstract
An X-ray radioscopy device comprises: an image capturing unit that captures a moving image of an object that has been irradiated by X-rays; an analysis processing unit that performs different analysis processes in parallel on each frame that makes up the moving image and extracts, from each frame, a region of interest defined as a portion of the object subject to radioscopy by the X-ray irradiation; and a selection unit that performs an evaluation operation on the multiple regions of interest extracted based on the different analysis processes, and based on the result of the evaluation operation, selects and outputs a single region of interest from the multiple regions of interest extracted by the analysis processing unit.
