Title:
情報コード及び情報コード復号方法
Document Type and Number:
Japanese Patent JP4838387
Kind Code:
B2
Abstract:
An information code of the present inventioncomprises an excision code portion based on a code system which allows easy excision, by colorcomponent analysis, of a code area from an image data containing the code area, and a data recording code portion which is capable of recording target electronic data in high recording density, and can improve recording density of the data recording code portion by increasing the number of colors and/or reducing the cell size, by decoding of the excision code portion making possible also using mathematical calculation not solely depending on color component analysis. The present invention aims to provide the information code based on two codestandards for the excision code portion and the data recording code portion respectively. A code system that provides easy excision of a code by the color component analysis is adopted for the excision code because the excision code serves as an initial clue to excise a code from an image. By decoding of the excision code portion, information needed for extraction and decoding of the data recording code portion is obtained.
