ABSTRACT:
To provide an electronically reproduced image of an original in which defects have been removed by retouching, defects in the original are marked in such a manner that the signals from an analysing scanner corresponding to the defect marking are distinguishable from those corresponding to the remainder of the original and the sensing of the defect-representing signals is used to cause a replacement signal, derived as a function of the densities of picture elements adjacent the defect in the original, to be substituted for the defect-representing signal before the train of signals from the analysing scanner is used to control the treatment of an output surface to form the image.
