PROBLEM TO BE SOLVED: To provide a creation program of hologram data for a projector device capable of reducing the number of optical elements for enlarging an image such as a zoom lens, and further reducing a load on diffraction calculation processing in scaling.SOLUTION: A hologram data creation program according to one aspect of the present invention causes a computer to apply shift Fresnel diffraction calculation processing on document image data to create hologram data. According to the aspect, the shift Fresnel diffraction calculation processing makes it possible to enlarge or reduce the document image data. |
