Abstract
An image acquisition unit acquires two radiographic images based on radiations which are transmitted through a subject containing a plurality of compositions and have energy distributions different from each other. A body thickness derivation unit derives, as a first body thickness and a second body thickness, body thicknesses of the subject for pixels of the two radiographic images. A composition ratio derivation unit derives composition ratios of the subject for the pixels of the radiographic images based on the first body thickness and the second body thickness.
