<p><P>PROBLEM TO BE SOLVED: To provide an image forming device monochrome copying a manuscript where special codes such as a plurality of QR codes (R) are included while saving an area on space where the special codes occupy, and separating and reproducing all the original special codes for a printed matter after monochrome copying. <P>SOLUTION: An MFP (Multi Function Peripheral) 1 reads N of two dimensional codes 21a, 22a, ..., and holds and connects data expressing that a cell is white or black at arrangement position (i, j) in each 2-dimensional code as C(1 i, j), C(2 i, j), ..., to generate N bit data D(i, j). According to a predetermined correspondence rule where each gradation color at the time of dividing lightness from white to black into gradation of Nth power individual of 2 is associated one to one with each pattern which N bit data can take, the MFP 1 determines a gradation color associated with D(i, j) and generates two dimensional code 23a which sets the determined gradation color to a color of the cell at the arrangement position (i, j). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
