An information input apparatus, an information input method, and an information input sheet which a user can easily operate without directly having to become aware of hardware are provided. An information input sheet includes a display area having an input information area and an identification area in which an identification code of the input information is provided. The identification code of the input information is provided in the display area as a target pattern having a rotation mode in which a code is defined by a directional orientation of the target pattern. An image pickup unit generates imaging information from imaging the information input sheet. The imaging information includes imaging information of the identification area of the information input sheet. Based on this imaging information of the identification area, the rotation mode of the target pattern, as recognized by an image recognition unit, is determined. The rotation mode specifies the identification code of the information input sheet. Information on the information input sheet is authenticated by authentication processing means.
