Abstract

A method and apparatus are disclosed for the coding of digital images for subsequent display by an apparatus having multiple image planes, wherein each image plane provides a unique information density. Accordingly, when an image feature is to be encoded, a determination is made as to whether it is possible to encode the image feature in a relatively lower density image plane or whether the feature must be encoded in a higher density image plane. A decoding system is likewise provided to interpret the encoded information for display on a display apparatus having multiple image planes.
