Abstract:
A method for reading and displaying a two-dimensional code is to enable the display of digital information with high cell density and to enable an accurate reading of digital information, while responding to the various conditions. An image pattern that can be distinguished from surrounding cells is detected from an image data containing the two-dimensional code by verifying an image on the image data with a predetermined verification pattern. The detected image pattern includes the image of one or more data marks.
