Claim Text:
1. A method for identifying a one- or two-dimensional barcode in input image data, the method comprising: obtaining first image data of a first image of an object, said first image being acquired from said object using a first illumination wavelength; obtaining second image data of a second image of said object, said second image being acquired from said object using a second illumination wavelength being different from said first illumination wavelength; calculating a weighting factor based on a statistical processing of pixel values of the first image data and pixel values of the second image data; and generating third image data by calculating a weighted combination using the pixel values of said first image data, the pixel values of said second image data, and said weighting factor, wherein said weighting factor is calculated for approximating the pixel values of said second image date to the pixel values in said first image data in an image background area excluding said barcode.
