1. A two-dimensional code generation method comprising:
- a binary data string generation step of generating a binary data string uniquely associated with given data based on the given data;
a point placement step of setting point placement reserved positions at each of which a point may be placed in a two-dimensional region, and placing a point at each of the point placement reserved positions in the two-dimensional region according to a preset binary data string placement condition based on the binary data string;
a connection step of connecting points placed in the two-dimensional region through a line according to a preset connection condition; and
an image generation step of generating an image of the two-dimensional code based on the line.

Abstract
A two-dimensional code in which given data is encoded as a two-dimensional image. The two-dimensional code includes as image elements: points each of which is placed at point placement reserved position in a two-dimensional region based on a binary data string uniquely associated with the given data according to a preset binary data string placement condition; and a line connecting each of the points and a connection target point according to a preset connection condition. The two-dimensional code is formed as a two-dimensional image by causing the line connecting the points to have a given width.

-
a binary data string generation step of generating a binary data string uniquely associated with given data based on the given data; a point placement step of setting point placement reserved positions at each of which a point may be placed in a two-dimensional region, and placing a point at each of the point placement reserved positions in the two-dimensional region based on the binary data string; and an image generation step of generating an image of the two-dimensional code based on the point, the point placement step including setting a main layer in the two-dimensional region, placing a point at part of the point placement reserved positions belonging to the main layer based on the binary data string, and placing a dummy point at another part of the point placement reserved positions belonging to a layer in the two-dimensional region other than the main layer.
