To provide an information processing device capable of suppressing deterioration of reading performance and durability to draw an image code even when a size of the image code varies.

The information processing device includes: magnification factor acquisition means to acquire a magnification factor of an area; a basic line number table; an additional line number table; line number determination means 53 which reads a basic line number corresponding to width information of an area included in an original image data from the basic line number table, reads an additional line number corresponding to the magnification factor from the additional line number table, and adds the additional line number to the basic line number to determine a line number to fill the area of magnified image data; overlapping width determination means 54 to determine information of overlapping width of an adjacent linear coloring range in drawing the magnified image data; output value information determination means 55 to determine information of an output value of a spot light in drawing the magnified image data; and position determination means 56 to determine start and end positions of the line to fill the area of the magnified image data on the basis of the information of the line number and the overlapping width.
