Method and device for picture-based barcode decoding

A device for picture-based barcode decoding, comprising:

• a memory for storing a captured image, a transformed image, a decoded data, an original data bitstream, and an original data;
• an image capturing device for capturing all or part of a picture as the captured image;
• a processor electrically connected to the image capturing device and the memory for executing the following steps:
• normalizing the captured image for generating the transformed image;
• calculating a mean color value of a plurality of blocks of the transformed image for generating the decoded data;
• performing an inverse error correction on the decoded data for generating the original data bitstream;
• transforming the original data bitstream into the original data;
• and
• outputting the original data with an output device.
