Abstract
An image processing system to allow communication with input and output devices having varying resolutions. An image processing system converts an image into a compressed base image and successive levels of error correction data so that an output of the image may be provided with any desired level of resolution (up to that of the input) with further levels of resolution obtained through predictive techniques. Advantageously, the error coding data is arithmetically coded.
