PURPOSE:To provide an image deforming method and device therefor capable of freely and smoothly deforming the image of a bit array form with a little memory capacity. CONSTITUTION:When the vertex (a moving reference grid point (p, q)) of an arbitrary small polygon inside a deforming object is moved to an arbitrary location where the small polygon is positioned again inside the object after a deformation at least, the vertexes of other small polygons are moved so that the whole of the deforming object may be smoothly deformed and the vertexes of other small moved polygons are calculated based on the vertex after the arbitrary small polygon is moved (a deforming moving grid point (xd, yd)). Subsequently, the shape of each small polygon after the deformation corresponding to each calculated vertex is determined, deformation processings are successively performed for original images so as to correspond to the data of the small polygon after the deformation and the whole of the image after the deformation is prepared. |
