A bar code perfect virtue coding and decoding system for largeness a volume the two dimension color which a color revision is possible and method thereof

摘要

The present invention system and restoring the on / off-line (On / Off-Line) environment, the original data from the system and method, and a two-dimensional bar code, the generated large color to generate the original data to the mass of the color two-dimensional bar code under It relates to a method. ; That is, the present invention compresses the original data and the error detection and after the addition the data for the correction method for generating a large color two-dimensional bar code, and large color two-dimensional bar code shape to make available in print via the print offline environment a bar code encoding system, a large color of the printed document the two-dimensional bar code produced from the encoding system that receives through input devices such as scanners and cameras include, recognition by searching the two-dimensional bar codes after color correction and error It performs detection and correction, and unzip it provides a decoding system, including how to restore the original data. ; Color, two-dimensional barcodes, markers, metadata, Maxi Code, QR Code
