    • A two-dimensional code recognition processing method for recognizing a two-dimensional code made of a plurality of square cells arranged in accordance with predetermined layout rules. The method comprises the steps of: generating binary data from image information acquired externally in accordance with a predetermined threshold value; detecting a reference cell serving as a reference in recognizing the two-dimensional code based on the binary data generated in the binary data generating step; detecting corner cells each located in a predetermined search range with respect to the reference cell detected in the reference cell detecting step, on the basis of the binary data generated in the binary data generating step; and detecting code data assigned to the two-dimensional code existing inside an area of a code part enclosed by the reference cell and by the corner cells on the basis of the binary data generated in the binary data generating step.
    • 一种二维码识别处理方法,用于识别由根据预定布置规则布置的多个方形小区构成的二维码。 该方法包括以下步骤:根据预定阈值从外部获取的图像信息生成二进制数据; 基于在二进制数据生成步骤中生成的二进制数据来检测用作基准的参考单元,用于识别二维码; 基于在二进制数据生成步骤中生成的二进制数据,检测相对于在参考单元检测步骤中检测到的参考单元位于预定搜索范围内的角单元; 并且基于在二进制数据生成步骤中生成的二进制数据来检测分配给存在于由参考单元包围的代码部分的区域内的二维代码和角落单元的代码数据。
