Abstract
In an image data compression system for encoding a binary or multilevel image signal into a compressed code, a line position is detected from the image signal and normalized, and its relative normalized line position is calculated from a line to be coded and an immediately preceding coded line, and then the relative normalized line position is encoded. Run positions (where pel values change) on the same line in the image signal are detected and normalized, and relative normalized run positions of adjacent one of the normalized run positions are calculated and encoded.
