Embodiment Construction

[0019] The following is a further explanation of the technical solution adopted by the method of generating QR codes through rendering: the generation method of rendering is to generate beautiful pictures according to the encoding results, and the method of ordinary QR codes is to use Black or white rectangular blocks. The key to the improved generation method here is not to use black or white rectangular blocks, but to use dark or light-colored pictures.

[0020] The first method is very straightforward, which is to directly replace the black rectangle block with a picture of the same size as the black rectangle block in the ordinary QR code, but there are multiple pictures that can be selected, and you can choose according to the specific situation. The white rectangle is replaced with a light background image. The grayscale value of the dark image should be above 150, and the grayscale value of the light image should be below 100, so as to ensure correct binarization durin...

Abstract

A method for generating quick response (QR) codes in rendering mode includes three independent methods or more than two combinations: using small blocks of pictures to replace each black-white block, the plurality of small blocks of pictures are selected as required; using pictures in different sizes to fill in different parts of QR code signs, simultaneously using rounded rectangles to replace the original square rectangles, and using circular pictures to fill in the independent black-white blocks; and using stereo pictures to display the QR codes. Normal QR codes are displayed with black-white appearance, and the method provides a more attractive mode to display the QR codes under the premise of not affecting recognition. Small icons can be covered on the QR codes generated in the method, so that the generated QR codes have specific features of users. Through the method, the originally monotonous QR codes can be displayed in a more abundant mode.

Description

technical field [0001] The invention relates to a picture generation process after QR code coding is completed, by proposing a picture filling method. technical background [0002] Two-dimensional code technology began to appear in the late 1980s. After more than 20 years of promotion and application, it has played a huge role in the fields of information management and information exchange in many industries. The domestic QR code market is also developing rapidly. As the barcode standard recommended by China Mobile, QR code was included in the business plan of China Mobile Data Department as early as 2004. China Mobile Enterprise Standard was formulated at the end of 2005 and included in China Mobile in 2006. Mobile terminal preset planning. However, QR codes have always been used in various industries in the form of black and white blocks. For specific individuals and businesses, a QR code with its own unique form is necessary.
