ABSTRACT:
An imaging apparatus receives a stream of image data compressed according to a token based compression algorithm. The token dictionary is decompressed and processed according to desired standards such as optimizing for a particular image output device. After revision, the revised tokens are stored in a revised dictionary which is accessed upon decompression of image content. When the image content is decompressed the locations in the compressed or coded input data stream refer to locations in the revised dictionary which are extracted and output either to hard copy or for further processing.
