Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] In order to intuitively describe the present invention, first use figure 1 exhibit the effects of the present invention. Divide the QR code into meshed sub-areas, such as figure 1 As shown, the size of the mesh sub-area can be adjusted according to the resolution of the two-dimensional code device. First, a specific sub-area is filled with color as a positioning color block, and the positioning color block is composed...

Abstract

The invention provides a method and apparatus for positioning a two-dimensional code content display area. The content display area of a two-dimensional code is divided into multiple subareas, a positioning color block is generated by filling the subareas by use of RGB colors, a display area of content to be displayed is determined, according to the display area of the content to be displayed and a preset positioning relation, a RGB color code and position information of the positioning color block are determined, the positioning relation refers to a corresponding relation between the display area of the content to be displayed and a two-dimensional array including the RGB color code and the position information of the positioning color block, the positioning color block is displayed according to the determined RGB color and the position information of the positioning color block, and information of the content to be displayed is displayed in the display area. According to the invention, the problem of quite low positioning security of content information display area of the two-dimensional code in the prior art is solved, and the security grade of the content information which can be carried by the two-dimensional code is improved.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a method and device for positioning a content display area of ​​two-dimensional codes. Background technique [0002] Two-dimensional code is to record data symbol information on the plane (two-dimensional direction) according to certain rules with a certain set of graphics, because it has large information capacity, wide coding range, strong fault tolerance, and high decoding reliability. With the characteristics of low cost and easy production, with the popularity of the Internet and mobile devices today, the application of two-dimensional codes in various fields is increasing day by day. Usually, two-dimensional codes are used to indicate content information by placing fixed positioning graphics in fixed areas The specific position of the data in the two-dimensional code graphic, after using the two-dimensional code reading device to read the content information d...
