A first acquiring unit acquires a background image being an image of a usage environment in which a printed material is used, a lighting image of a lighting installed in the usage environment, and light source information indicating an optical attribute in the usage environment. A second acquiring unit acquires print data. A display control unit displays a preview image on a display unit, where the preview image is an image in which a printed material image is superimposed on the background image, and the printed material image is an image in which the lighting image is mapped by environment mapping onto a print-image display surface generated based on the print data and in which the optical attribute specified by the light source information is set.
