Abstract
For facilitating detecting the position of additional information embedded in image information shown on a printed matter, an input unit configured to input image information and an embedding unit configured to embed a plurality of code patterns in the image information according to additional information are provided. The additional information includes direction-determination information used to detect the direction in which the additional information is embedded in the image information. When one of the code patterns is rotated, the rotated code pattern corresponds to one of the code patterns that are not yet rotated.
