ABSTRACT:
Two-dimensional code having superior decoding property making it possible to control the level of error correcting codes, and a method for encoding and decoding the two-dimensional code is provided. The two-dimensional code includes a finding pattern area comprised of finding patterns for discriminating the code area from the whole image, a timing pattern area comprised of timing patterns for checking a position of the data area from the whole code and the position of each cell of the data area, and a data area being inputted with various kinds of data and decoding information.
