Abstract
A method for generating a color QR code includes: generating a grayscale image according to a color image; providing a QR code and dividing the grayscale image into the number of grayscale image modules matching module numbers of the QR code; generating a threshold mask image from grayscale image modules; cutting out each center block from center part of each grayscale image module and calculating characteristics values of the center blocks; identifying color of each module of the QR code, and comparing the characteristics values of the center blocks of the grayscale image to the corresponding threshold value compensated by robustness value to identify center blocks needing pixel luminance adjustment; dividing the center blocks needing pixel luminance adjustment into multiple layers of blocks; adjusting pixel luminance of the multiple layers of blocks using the robustness value times with corresponding weightings; and generating a fused color QR code.
