Abstract:
1. A device for generating an image code comprising: an encoding unit generating a two-dimensional image by configuring basic information including at least one of a letter, a number, a symbol, and an image, and error correction information for correcting an error in the basic information, encoding the configured basic information and the error correction information, and disposing the encoded basic and error correction information in predetermined regions, respectively; a decoding determination unit determining whether the two-dimensional image can be decoded in directions which are different from a basic direction of the two-dimensional image, respectively; and a code generation unit outputting the two-dimensional image as a physical or electronic image code when a result of decoding in the directions which are different from the basic direction of the two-dimensional image is the same as a decoding result for the basic direction, or when decoding cannot be performed in a direction which is different from the basic direction.
