Problems solved by technology

However, there are problems that when analyzing the image read by the reader, the implanted image of the light and shade unit is read as a meaningless character string, or the position of the implanted image is limited to the center of the two-dimensional code, etc.
However, this method has the following problems: in order to overlap patterns of a certain size, the error correction of the RS symbol becomes larger, thereby reducing the amount of data that can be stored; Weakened responses to damage and ambiguity when reading

Embodiment Construction

[0051] Before describing the embodiment of the present invention, a general two-dimensional code widely used at present will be described.

[0052] figure 1 It is a figure which shows the two-dimensional code described in patent document 1.

[0053] like figure 1 As shown, the two-dimensional code 1 has three position detection patterns (marks for positioning) 2 and a data area 3 arranged at three corners. The data area 3 is a part obtained by removing the three position detection patterns 2 and the surrounding isolated parts from the area of ​​the two-dimensional code 1 . Each position detection pattern 2 has a square frame 2a as a dark part, a square 2c arranged inside the square frame 2a, and a square frame 2b as a bright part between the frame 2a and the square 2c. When the captured position detection pattern 2 passes through the center, no matter which direction the scanning line takes, its length ratio (frequency component ratio) is dark:bright:dark:bright:dark=1:1:3:1:...

Abstract

Disclosed is a two-dimensional code having improved design characteristics, for which any image can be added. The disclosed two-dimensional code divides data displayed in binary code into cells, arranges same as a pattern in a two-dimensional matrix, and has a position detection pattern. The two-dimensional code has embedded design information that indicates the existence of design areas wherein any design can be arranged and, if a design area exists, the position of the design area.

Description

technical field [0001] The present invention relates to two-dimensional codes. Background technique [0002] Compared with one-dimensional codes, two-dimensional codes can carry more information in a small area, and are widely used in various purposes such as item management and network guidance using mobile phones. [0003] A typical two-dimensional code is formed by unitizing data represented by a binary code, arranged as a pattern on a two-dimensional matrix, and includes: a position detection pattern for reproducing coordinates in the code; and a data portion. The data part further includes version information, format information, position correction patterns, error correction codes, etc., and an actual data part in which coded message data is recorded. Therefore, only unitized data is recorded in the two-dimensional code. [0004] There is a need to add arbitrary patterns to the two-dimensional code. For example, when printing two-dimensional codes on magazines, post...
