Abstract
A two-dimensional code that is capable of suppressing unnecessary code detection processes related to detection of a code area is provided. Among outer edges of a rectangular code area, a first edge that is composed of a plurality of types of cells arrayed in a single row is configured such that a specific pattern that is composed of an array of two or more differing cells is repeated in at least an intermediate portion. A second edge composed of the plurality of types of cells arrayed in a row such as to oppose the first edge is configured such that the specific pattern is repeated in at least an intermediate portion.
