20090166418 | Layered two-dimensional code, creation method thereof, and read method - The present invention provides a layered two-dimensional code which can be considerably improved in the data capacity thereof without increasing the area thereof by integrating a plurality of two-dimensional codes by a predetermined correlation and expressing it as one two-dimensional code, a method of creating the layered two-dimensional code, and a method of reading the layered two-dimensional code. The layered two-dimensional code is formed as a surface layer by layering a plurality of code layers (for example, code layers | 07-02-2009 |
20090057420 | Clear Two-Dimensional Code, Article Having Clear Two-Dimensional Code Attached Thereto, Method for Printing Two-Dimensional Code and Method For Displaying Two-Dimensional Code - The present invention relates to a clear two-dimensional code which can be merged with an image without giving a user a feeling of disorder when the clear two-dimensional code is attached to the image and in which a readable situation and the like can be arbitrarily set; an article having the clear two-dimensional code attached thereto; a method for printing the two-dimensional code; and a method for displaying the two-dimensional code. Base cells and data cells are arranged in a matrix, and either the base cells or the data cells are clear. The clear two-dimensional code can be read only when a color shown on the clear cells consisting of either the base cells or the data cells and a color shown or non-clear cells consisting of either the base cells or the data cells have a contrast which can be read by a code recognition apparatus. | 03-05-2009 |
