    • 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.
    • 提供一种用于从物理或电子表示的代码图像中识别代码并提取代码图像中表示的数据的装置和方法。 该方法包括以下步骤:接收包含代码图像的原始图像,检测原始图像中包括的背景图像,提取其中排除背景图像的代码图像区域,识别代码图像的形状和类型 以及在每个单元格中表示的颜色或阴影,将从每个单元识别的颜色或阴影转换为相应的字符,数字或符号并生成代码数据。 接收预定数据被表示为颜色或阴影的代码图像,并且无论识别代码图像的环境如何,都可以精确地识别原始颜色或阴影。
