It is necessary to illuminate a specific portion at a specific angle. However, it is difficult to perform light irradiation at a specific angle by scanning, and it is also difficult to perform light irradiation only to a specific portion.

On the other hand, in order to prevent the forgery of identity cards, micro-printing techniques are used to engrave characters of less than 1 mm, or micro-texts (and patterns) in which flat-panel texts are printed with patterns, most of which are printed. However, in the case of conventional scanning methods, The general resolution is around 600 dpi, and there is a problem that such micro-text (and patterns) cannot be recognized.

There are also images made with optical identification ink on the ID card, holographic images that appear or disappear according to the viewing angle, and patterns and photos printed with fluorescent ink that will illuminate under ultraviolet or white light (hereinafter referred to as It is an "auxiliary pattern"). However, the conventional invention has a problem that it is impossible to recognize that the holographic image has various appearances depending on the angle of illumination.
