Abstract

A method for supplementing a digital image with picture elements, by which prediction signals having small errors can be generated for a digital image in which objects move greatly through a process which does not cause a long delay time and does not need a large quantity of calculation. In the method, the image is divided into areas. The insignificant sampled values of the areas containing the boundary of the shape of an object are transformed with a function of significant picture element values near insignificant picture element values and used to supplement the digital image. A digital image encoder and a digital image decoder both using the method are also disclosed.
