Chinese-sensible code barcode decoding chip and decoding method thereof

The invention provides a Chinese-sensible code barcode decoding chip. A feature searching unit searches a feature figure in a barcode image to determine a pixel coordinate of the feature figure. A barcode parameter acquisition unit acquires a barcode parameter according to the pixel coordinate of the feature figure. An edition/format parameter acquisition unit acquires an edition parameter and/or a format parameter of a barcode. A correction feature acquisition unit searches a feature position on the barcode figure and acquires a correction feature according to the feature position. A module information processing unit calculates a gray value corresponding to a module according to the edition parameter, the barcode parameter and the correction feature. A binaryzation unit carries out binaryzation processing on a code word. A code word extracting unit extracts the code word according to the module subjected to the binaryzation processing. An error correction decoding unit decodes the code word. The invention a
