摘要： An apparatus and method for recognizing a code from a code image that is expressed physically or electronically and extracting data represented in the code image is provided. The method includes the steps of receiving a raw image in which a code image is contained, detecting a background image included in the raw image, extracting a code image region in which a background image is excluded, recognizing the shape and type of the code image and the color or shade represented in each of cells, converting the color or shade recognized from each of the cells into a corresponding character, number, or symbol and generating code data. The code image in which predetermined data are represented as colors or shades are received, and original colors or shades can be precisely discriminated regardless of an environment in which the code image is recognized.

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.
摘要翻译：提供了一种用于生成和解码没有取景器图案的图像代码的方法和装置。在生成图像代码的方法中，通过对配置的基本信息和纠错信息进行编码来生成二维图像，并将编码的基本和纠错信息分别布置在预定区域中。确定二维图像是否可以针对与二维图像的基本方向不同的方向进行解码，并且当解码的结果分别将二维图像作为物理或电子图像代码输出因为与二维图像的基本方向不同的方向与基本方向的解码结果相同，或者不能对与基本方向不同的方向进行解码时。在解码图像代码的方法中，以物理或电子方式表示的图像代码作为输入被接收，并且输出解码结果具有从每个方向解码的结果中具有最少错误数的方向的解码结果。因此，可以在没有任何开销或最小开销的情况下检测图像代码的方向。
