Abstract
Abstract Main image information representing a portrait face image of a person is prepared. Predetermined pattern image information, used as sub image information, is also prepared. Synthetic image information is prepared by synthesizing the main image information with the pattern image information in such a manner that the pattern image information is embedded in the main image information in a state that is not recognizable to the eye of a human being. This synthetic image information is recorded on an ID card or the like as a visible image.

Independent Claim
188 words
An information processing method for embedding a pattern image in a main image in such a state that is not recognizable to the naked eye of a human being, comprising: preparing main image information that is recognizable to the naked eye of a human being; preparing pattern image information; executing color difference modulation processing for the pattern image information in accordance with a color modulation amount, such that a first color alternates with a second color complementary thereto; superimposing the pattern image information modulated in color difference by the color difference modulation processing on the main image information, thereby preparing synthetic image information such that a synthesized state is not recognizable to the naked eye of the human being; and recording the synthetic image information on a recording medium as a visible image; wherein existence of the pattern image in the recording medium becomes recognizable to the naked eye of a human being when the synthetic image information recorded on the recording medium is physically superimposed with and moved relative to a mask sheet having the same pattern of light transmission distribution ratio as the pattern image information.
