Abstract:
1. An image processing device comprising: an acquiring unit that acquires invisible image data of an invisible image subject to forming on a recording medium with invisible coloring material having absorption wavelength characteristics wherein light within visible wavelengths is at least partially absorbed, an overlapping region calculating unit that calculates an overlapping region of an image of the invisible data and an image of the source image data; and a generating unit that generates corrected-image-data of a pixel within the overlapping region of the source image data corrected according to the absorption wavelength characteristics, such that a color of the pixel within the overlapping region, where both a pixel of the invisible image and a pixel of the source image are superimposed when formed on the recording medium, is at least nearly an identical color to a color of the pixel of the source image within a region corresponding to the overlapping region.
