Apparatus and method for restoring bar code image

The present invention proposes a bar code image decoding device and method for performing non-uniform illumination prediction with a bar code de-blurring when restoring relates to a bar code image decoding device and method, a bar code image as associative. Bar code image decoding device according to the present invention, the observation unit for observing the input bar code image; Modeling unit for including each of the function representing the blur kernel and the non-uniform illumination causing the distortion in a given bar code image, the specific image of the bar code as a component model any bar code image; And may include portions to restore to restore the bar code image of the modeled and optimized by the observation of the modeled bar code image so that the larger the degree of similarity between the observed image the bar code the bar code image, correctly to restore the bar code image. Barcode imaging, non-uniform illumination, blur, binary image
