ABSTRACT:
A method and apparatus for encoding an original image. A first error image is formed from the original image and a first predicted image. A second error image is formed from the original image and a second predicted image. The first error image is resolved into at least one lower resolution image which is encoded. An expanded image is formed based on the encoded lower resolution image, the expanded image being of the same level of resolution as the second error image. An image representative of the difference between the second error image and the expanded image is encoded at full resolution.
