Abstract

A method of and device for forming X-ray images in which a charge pattern corresponding to the X-ray intensity generated on the surface of a photoconductor is line-wise scanned by a number of probes which detect the charge in respective adjoining scanning zones of the photoconductor containing a plurality of lines eliminates stripes occurring in the line direction in the image. This is accomplished by: a) formation of correction values (K.sub.n (x,y.sub.o)) for the pixels of the image line (y.sub.o) at the edges of the scanning zones of the probes (41), the absolute value and sign of the correction values being such that corrected image values (B.sub.kn (x,y.sub.o)) of the individual probes, resulting from the superposition of the correction values and image values (B.sub.n (x,y.sub.o)), correspond to the corrected image values of the respective neighboring probes; b) formation of intermediate values (Z.sub.n (x,y)) for the image lines (y) situated between the edges of the scanning zones of the probes by interpolation of the correction values (K.sub.n (x,y.sub.o); K.sub.n (x,y.sub.u)) associated with the same probe; and c) superposition of the correction values, or the intermediate values, and the image values in order to produce corrected image values for the image lines of the scanning zones.
