1. A method for picture-based barcode encoding, comprising:

  • transforming an original data into an original data bitstream;

    performing an error correction on the original data bitstream for translating the original data bitstream into an error corrected bitstream;

    selecting all or part of the picture as an encoded area;

    calculating a data storage capacity of the encoded area;

    adjusting a size of the error corrected bitstream or a size of the encoded area for equalizing a data storage capacity of an encoded data bitstream and the data storage capacity of the encoded area; and

    adjusting a pixel value of the encoded area according to the encoded data bitstream.
