DEVICE, METHOD, AND PROGRAM FOR CREATING A TWO-DIMENSIONAL BARCODE IMAGE, SYSTEM AND METHOD FOR INFORMATION TRANSMISSION, AND DEVICE, METHOD, AND PROGRAM FOR DECODING THE TWO-DIMENSIONAL BARCODE
A two-dimensional bar code image generation apparatus for generating a color image according to a two-dimensional bar code comprises a two-dimensional bar code encoding section 11 that encodes the input information into a two-dimensional bar code, an up-sampling section 12 that up-samples the two-dimensional bar code, a luminance signal generating section 13 that applies a band limit to the output of the up-sampling section and outputs the band-limited output as luminance signal and a blue color difference signal generating section 14 and a red color difference signal generating section 15 that output the quantity of variance between any two adjacent pieces of information respectively as a blue color difference signal and as a red color difference signal in the output of the up-sampling section.
