ABSTRACT:
An image transforming device transforms images by transforming video signals into a spatial frequency range, by frame-interpolating the transformed signals in the spatial frequency range and by reversely transforming such signals. In such a device, a portion moving isolated in a frame can be frame-interpolated in such a manner that the isolated motion is dispersed over the entire frame. Thus, even when a frame contains an isolated moving portion, the device can provide a natural image, effectively avoiding degradation of image quality.
