The invention relates to an image conversion method and to an apparatus for converting a digital image obtained by a scanning unit into a converted digital image. The method comprises the steps of acquiring statistics for at least some pixels of the digital image, extracting characteristic values of a background colour using the acquired statistics, operating a selection of pixels in the digital image, each pixel in the digital image being sequentially set as a target pixel, and converting the selected pixels. The method is characterised in that the selection of the target pixel depends on a representative colour distance determined between a number of pixels located in a vicinity of the target pixel and the background colour. |
