Two-dimensional code with changeable coloring pixel zone, and generating method and apparatus for two-dimensional code with changeable coloring pixel zone

Abstract

Disclosed in the invention is a generating apparatus for a two-dimensional code with a changeable coloring pixel zone. The generating apparatus is composed of a data reading module, a bit stream generation module, a position determination module, and a drawing module. To be specific, the data reading module is used for reading to-be-coded binary data and a preset pixel compression ratio. The bit stream generation module is used for generating a bit stream sequence including a functional graph code and an effective data code according to the read to-be-coded binary data. The position determination module is used for determining a position of binary data of a current bit in a two-dimensional code graph and sending the determination result to the drawing module. The drawing module is used for receiving the determination result from the position determination module and drawing a deep color pixel zone with a reduced area based on the preset pixel compression ratio for a binary bit corresponding to the to-be-coded binary data in a non-position detection graph according to the determination result. With the provided generating apparatus, a color data module area of a generated quick response (QR) code can be reduced and thus a blank area of a QR code graph can be increased, so that embedding into a LOGO or background pattern can be realized conveniently and thus the viewable area of the LOGO or background pattern can be increased.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a two-dimensional code with variable colored pixel areas and a generating method and device thereof. Background technique [0002] Quick Response Matrix Code (QuickResponseCode, referred to as "QR Code") is a matrix two-dimensional barcode, figure 1 A schematic structural diagram of a QR code according to the prior art is shown. A QR code is a type of barcode. Such as figure 1 As shown, the standard QR code is composed of 4 positioning codes with known positions and black and white code points in the area defined by three of the large frame positioning codes. The code points are arranged by small squares with a specific size ratio. figure 2 A schematic diagram of generating a QR code according to the prior art is shown, wherein the matrixed encoding format reflects corresponding data information. Such as figure 2 As shown, when the small square is b...

AI Technical Summary

Problems solved by technology

Existing methods will be limited by the area of ​​the central area of ​​the “cutout” in advance. If the “cutout” area is too large, the QR code will become unrecognizable, and the logo or background pattern can only be placed on a small QR code. Therefore, the placement area provided by the existing method for LOGO or background pattern is limited by the "cutout" area provided by the QR code. If the "cutout" area is too small, it will affect the display of LOGO or background pattern Effect
