Positions of marker images included in two images obtained by a digital radiography system are detected by a marker position detecting section. The marker image intervals in each image are calculated by an extension rate correcting section in accordance with the detected positions of the marker images. Reduction/extension for one image is perfomed in accordance with the extension rate of the image obtained by a ratio of the calculated marker image intervals, thereby coinciding extension rates of two images.
