发明名称 Method of embedding a plurality of different two-dimensional codes in an image
摘要 The purpose of the present invention is to prevent a two-dimensional code to be additionally embedded from corrupting a two-dimensional code which has been embedded when a document in which the two-dimensional code has been embedded is copied or when a document in which the two-dimensional code has been embedded is overlaid on form data in which the two-dimensional code has been embedded. In the present invention, when it is detected that a second two-dimensional code is embedded in an input image, the input image is printed without overlay of a first two-dimensional code thereon. Furthermore, when form data for overlaying is stored, when it is detected that a third two-dimensional code is embedded in the form data or when it is detected that a second two-dimensional code is embedded in an input image, the input image is output without overlay of a first two-dimensional code thereon.
