Embodiment Construction

[0034] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the drawings and specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the specification of the present invention in this specification are only for the p...

Abstract

The present invention provides a method and device for generating a color two-dimensional code. The generating method includes the following steps: pre-setting the identification area of ​​the color two-dimensional code, the identification area includes a positioning area and an information area; pre-setting the color two-dimensional code The number of colors of the two-dimensional code; obtaining the data to be encoded; the encoding step: encoding the data to be encoded, generating an information code element with the number of colors, and outputting the identification area of ​​the data to be encoded. With the above scheme, the present invention redefines the new color two-dimensional code by using the number of colors, which can carry more code-carrying information, has a large amount of information storage, and is conducive to accurate identification. It can be used as a text or image carrier and has a high market. Value.

Description

Technical field [0001] The invention relates to a color two-dimensional code, and in particular to a method for generating a color two-dimensional code. Background technique [0002] Two-dimensional bar code / two-dimensional bar code (2-dimensional bar code) uses a certain geometric figure to record data symbol information in a black and white pattern distributed on a plane (two-dimensional direction) according to a certain rule; ingenious in coding Utilize the concept of "0" and "1" bit stream that constitute the internal logic of the computer, and use several geometric shapes corresponding to binary to represent text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment. Automatic information processing: It has some common features of barcode technology: each code system has its own specific character set; each character occupies a certain width; it has certain verification functions, etc. At the same time, it al...
