The edge processing process converts an original image into a binarized input image. The QR code positioning process includes a group search process and a tag search process. The group search process includes: deriving a plurality of luminance groups according to luminance values of pixels within an input image; identifying a plurality of finder pattern groups complying with QR code finder pattern among the plurality of luminance groups according to a central point of each luminance group; and deriving position information of each finder pattern group. The tag search process derives position information of the QR code according to the position information of the finder pattern groups. The projection modification process converts the input image into a modified image according to the position information of the QR code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"QR code processing method and apparatus thereof","description":"A QR code processing method includes an edge processing process, a QR code positioning process and a projection modification process.
