Abstract
A composite two-dimensional code according to an embodiment of the present invention is a combination of a first two-dimensional code and a second two-dimensional code. The composite two-dimensional code includes a first cell having a first color, a second cell having a second color, and a third cell having a third color. The first color, the second color, and the third color are different from each other. The first two-dimensional code is acquired by a first filtering processing. The second two-dimensional code is acquired by a second filtering processing.
Claims16
A composite two-dimensional code in which a first two-dimensional code and a second two-dimensional code are combined, comprising:
- a first cell having a first color;
- a second cell having a second color;
- and
- a third cell having a third color,
- wherein the first color, the second color, and the third color are different from each other,
- wherein the first two-dimensional code is acquired by a first filtering processing,
- wherein the second two-dimensional code is acquired by a second filtering processing,
- wherein the first filtering processing is a processing of converting the second cell having the second color of the composite two-dimensional code,
- wherein the second filtering processing is a processing of converting the first cell having the first color,
- wherein the first two-dimensional code comprises the first cell having the first color and the third cell having the third color,
- wherein the second two-dimensional code comprises the second cell having the second color and the third cell having the third color, and
- wherein the first two-dimensional code comprises count information about a number of first cells having the first color in the composite two-dimensional code.
A composite two-dimensional code in which a first two-dimensional code and a second two-dimensional code are combined, comprising:
- a first cell having a first color;
- a second cell having a second color;
- and
- a third cell having a third color,
- wherein the first color, the second color, and the third color are different from each other,
- wherein the first two-dimensional code is acquired by a first filtering processing,
- wherein the second two-dimensional code is acquired by a second filtering processing,
- wherein the first filtering processing is a processing of converting the second cell having the second color of the composite two-dimensional code,
- wherein the second filtering processing is a processing of converting the first cell having the first color,
- wherein the first two-dimensional code comprises the first cell having the first color and the third cell having the third color,
- wherein the second two-dimensional code comprises the second cell having the second color and the third cell having the third color, and
- wherein the first two-dimensional code comprises percentage information about a percentage of first cells having the first color in the composite two-dimensional code.
