1. 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.
