摘要： A method and device for generating and decoding an image code without a direction finder pattern are provided. In the method of generating an image code, a two-dimensional image is generated by encoding the configured basic information and the error correction information, and disposing the encoded basic and error correction information in predetermined regions, respectively. It is determined whether the two-dimensional image can be decoded for directions which are different from a basic direction of the two-dimensional image, respectively, and the two-dimensional image is output as a physical or electronic image code when a result from decoding for 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 for a direction which is different from the basic direction. In the method of decoding an image code, a physically or electronically represented image code is received as an input, and a decoding result for a direction for which the decoding result has the least number of errors from among the results decoded for each direction is output. Accordingly, a direction of an image code can be detected without any overhead or with a minimal overhead.

摘要： Provided are a method and apparatus for decoding a mixed code that is a combination of first and second code images. In the method, a mixed code image is obtained by receiving the original image having the mixed code image and removing noise from the original image. Next, the colors, shades, and brightnesses of pixels of the mixed code image are categorized into groups based on a predetermined threshold, the mixed code image is divided into first and second code images, and first and second information are extracted by decoding the first and second code images, respectively. The first and second code images can be effectively decoded by decoding interpretation information, construction information, error control information, and code direction information stored in the first and/or second code images.
