A rasterized image detected by a sensor is subdivided into areas wherein a respective grey-scale threshold value is set for the purposes of a decision according to which a pixel with a grey-scale value above or below said threshold is allocated the value 1 or 0 . Said binarization is carried out for different subdivisions of the aforementioned image, whereby the results thereof are additively superimposed, in order to obtain an interference-free pixel mask . Said mask is used in order to reproduce the interference-free pixels of the initial image and to allocate the grey-scale values of the remaining pixels. |
