Abstract

In this two-dimensional code, data expressed in binary code is divided into cells, and arranged as a two-dimensional matrix-like pattern. The two-dimensional code is characterized by being provided with a basic pattern section, and a peripheral section arranged outside the basic pattern section. The two-dimensional code is further characterized in that the basic pattern section includes: position detection patterns for specifying cell positions; and basic-pattern-section movement information indicating the position of the basic pattern section in the two-dimensional code area.

Claims

1. A two-dimensional code comprising cells representing binary-coded data that are arranged as a pattern in the form of a two-dimensional matrix,

wherein

the two-dimensional code comprises:

a basic pattern section; and

a peripheral section arranged outside the basic pattern section, and

the basic pattern section comprises;

position detection patterns for specifying cell positions; and

basic pattern section displacement information that indicates a position of the basic pattern section in the two-dimensional code region.

2. The two-dimensional code according to claim 1, wherein the basic pattern section displacement information is basic pattern section displacement amount information that indicates the amount of displacement of the basic pattern section from a prescribed position.

3. The two-dimensional code according to claim 1, wherein the basic pattern section displacement information is basic pattern section position information that indicates the position of the basic pattern section in the two-dimensional code.

4. The two-dimensional code according to claim 1, wherein the basic pattern section displacement information comprises a basic pattern section displacement flag that indicates the presence or absence of displacement of the basic pattern section from a prescribed position.

5. A system for analyzing the two-dimensional code according to claim 1, the system comprising:

a detection means for determining the coordinates of the basic pattern section based on the positional relationship of the position detection patterns and detecting the basic pattern section displacement information; and

an actual data analysis means for analyzing actual data composed of encoded messages,

wherein the actual data analysis means detects the actual data determined based on the result of detecting the basic pattern section displacement information.

6. A system for generating the two-dimensional code according to claim 1, the system comprising:

a means for generating specification data for determination of the cell arrangement in the peripheral section of the two-dimensional code;

a means for generating actual data composed of encoded messages;

a means for arranging the basic pattern section displacement information; and

a means for arranging the actual data at least in the peripheral section.
