Abstract: Disclosed herein are a bar code encoding system and a bar code decoding system. The bar code encoding system includes a method for compressing the original data and adding data for error detection and correction to the compressed data to generate a large capacity 2-dimensional color bar code so as to be used as prints in an off-line environment and a large capacity 2-dimensional bar code pattern. The decoding system includes a method for receiving the prints including the 2-dimensional bar code generated by the encoding system through an input device such as a scanner and a camera, searching the 2-dimensional bar code to recognize it, performing color correction and error detection and correction, decompressing the compressed data to decode the original data.

Abstract: The present invention relates to a code recognition voice-outputting device, in which a digital code image of a predetermined compression type is recognized, and the recognized image is converted into voice to be output to the outside. The apparatus includes a reader as a scanning unit for recognizing a compressed digital code image, and a player for processing the digital code image read from the reader, and converting the processed code image into voice to be output to the outside, wherein the reader and the player are configured to be capable of being separated from each other. The present invention further provides a code recognition voice-outputting device which supports a variety of functions and provides a voice guide function for all menus and operating statuses that support the functions for the sake of eyesight handicapped, illiterates, the aged, etc., thereby promoting user convenience.
