An original picture of an interlace system is magnified or reduced by an integer ration of M to N to form a conversion picture. A unit length U is obtained by dividing the distance between vertically adjacent picture elements of the original or the conversion pictures by N or M, respectively. The positions of the picture elements of both fields of the conversion picture are shifted by .vertline.M-N)/4.vertline..multidot.U from the respective positions that would have been occupied by the picture elements of the conversion picture.
