Abstract
In an image processing apparatus and method, a color copying interface supports unique compression mode and standard compression mode. If a color work station accepts only data compressed in the standard mode, unique-mode compressed data is converted to standard-mode compressed data, and then the standard-mode compressed data is transmitted together with a compression parameter to the partner computer. The amount of input data is counted by a counter, and the amount of compressed data stored in a compression memory is counted by another counter. Compression parameters used by a compression circuit are selected based on the count values of the two counters.
