PROBLEM TO BE SOLVED: To provide a three-dimensional preview function for displaying (reproducing) a printed matter with improved texture including gloss.SOLUTION: A value Rpa(Paa×Par) of a ratio of applying a sheet-part regular reflection data is determined from a value Paa of sheet-part regular reflection application area data 203 in a position 302 of interest in document data 200, and sheet-part regular reflection application ratio data 304 in a position indicated by a reflection vector 303. A sheet regular reflection component CPspe(Rpa×Pspec) is determined from the ratio value Rpa and a sheet-part regular reflection data value Pspec in the position of interest. An image regular reflection component is determined in the same way, to calculate a preview data value in the position 302 of interest in the document data, from a diffusion reflection component, a sheet regular reflection component, and an image regular reflection component. |
