Abstract
PURPOSE:To suppress a notch, and to improve picture quality, by detecting the protrusion, or the omission of one picture element on an image from a reference pattern, expanding it with a low magnification ratio, and expanding the data of the picture element that is not the protrusion or the omission, with a high magnification ratio which expands the original one picture element to the several number of picture elements. CONSTITUTION:The titled device is provided with an image pattern data reading means 500 which updates in order, end reads out in order a noticed picture element setting bit data corresponding to each of at least eight picture elements adjacent to the noticed picture element as a reference pattern. And the protrusion, or the omission of one picture element on the image is detected from the reference pattern, and it is magnified with the low magnification ratio, and the data of the picture element that is not the protrusion, or the omission is expanded with the high magnification ratio which magnifies the original one picture element to the several number of picture elements. In such a way, the picture data of a part without having the notch is expanded with a set magnification ratio, and the notched part of it is expanded with a ratio lower than the set magnification ratio, therefore, the notch is compressed and is not conspicuous in an expanded picture data obtained in such a way, because the magnification ratio for the notch is set at a low ratio.
