1. An information processing apparatus for registration of information related to a latent image and information related to a background at an image processing apparatus that outputs an image of a ground tint including a latent image and a background, comprising: a storage unit storing an image pattern of a background and an image pattern of a latent image, an operation unit accepting an externally-applied operation, a pattern selection unit selecting an image pattern of a background and an image pattern of a latent image from image patterns stored in said storage unit, a ground tint generation unit generating image data of a ground tint using the image pattern selected by said pattern selection unit from the image patterns stored in said storage unit, a display control unit causing a display device to display the image data of the ground tint generated by said ground tint generation unit, and a registration unit registering image patterns of a latent image and a background constituting the ground tint displayed by said display device at said image processing apparatus, based on acceptance of a predetermined operation by said operation unit.
