ABSTRACT:
A method and circuit arrangement for reducing the prominence of the scanning lines of an enlarged television picture by adding a plurality of scanning lines to an original television picture signal to form a modified picture signal, and supplying each added line with picture information from an adjoining one of the picture lines of the original television picture signal. This technique is applicable to television sets in which the pictures are stretched, in order for pictures having a different size and shape from that of the television screen to be shown in such a way that they fill the screen completely.
