ABSTRACT:
In a process of geometrically deforming an original picture by changing the picture element pitches, weight coefficients g calculated for the picture elements according to preselected magnification variation factors are read out of a first memory whenever original picture data F are read successively, the contents Fg of a second memory are read out according to addresses defined by the data g and F, and the addition result of the data Fg is divided by the addition result of the data g, thereby to obtain a geometrically deformed picture from the original picture.
