<P>PROBLEM TO BE SOLVED: To provide a program and a device for generating a background pattern for which a user can adopt an optional camouflage pattern. <P>SOLUTION: A background pattern image generation program generates image data of a background pattern composed of a latent image part and a background part whose output densities are different from each other when the background pattern is copied, and includes a camouflage pattern combining process (S46) in which first camouflage pattern data is inputted (S40) and combined camouflage pattern data is generated by combining the first camouflage pattern data and a second camouflage pattern having many shading change areas, and a background pattern image data generation process in which latent image part image data is generated based on a latent image part screen in an area corresponding to the latent image part and background part image data is generated based on a background part screen in an area corresponding to the background part with respect to a gray scale value of the combined camouflage pattern data. <P>COPYRIGHT: (C)2010,JPO&INPIT |
