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.
Claims10
A two-dimensional code comprising:
- a finding pattern area including finding patterns to discriminate a code area from a whole image;
- a timing pattern area including timing patterns to check a data region position and each cell in a data region from a whole code image, said timing pattern area being configured on three sides of said whole code image;
- and
- a data area having recorded various kind of predetermined data and decoding information.
