Abstract
A data compression method for an image processing system suitable for compressing image data containing a number of all white lines. Concurrently with the writing of a line memory, a circuit detects a set of adjacent all white lines, which are represented by all zeros. When such a set is detected, a special line boundary code and a code indicating the number of lines in the set are inserted into the image data, which is then applied to a compressor. When the compressor detects the special line boundary code, the compressor discards the corresponding image data, and generates an output for the line consisting of only the uncompressed line boundary code.
