Claim One:
1. The method for reproducing images with a coarser resolution than the image, which is scanned, whereby the original image is opto-electronically scanned point-wise and line-wise with a predetermined resolution to obtain digital image signals, wherein a field which contains as many fine image points as are included in a coarse image point is extracted from the digital image signals, wherein the individual image signals of the fine image points of said field are weighted with a weighting function and wherein the weighted image signals are combined to obtain the image signal for a coarse image point, the weighting and combination of the image signals comprising, serially weighting the fine image points point by point, storing the first weighted image signal, reading out the first weighted image signal, adding and storing the second weighted image signal to the previously read out first weighted image signal, reading out the sum of the first and second weighted signals, adding and storing the sum of the first and second weighted signals with the next weighted signal and repeating this reading out and adding process until the last weighted image signal of the field is processed and weighting the final sum of the weighted fine image points according to the number of the fine image points of the field.
