Abstract
A data compression apparatus includes a dictionary buffer for holding data of the immediately preceding line of successively inputted two-dimensional image data, a buffer for extracting a plurality of continuous data strings from the inputted data of the current line to store them as a partial data string to be compressed, a scanning comparison section for detecting whether or not the same data string as the partial data string to be compressed exists in the data stored in the dictionary buffer, and a code generator by which in the case where the presence of the same data string is detected by the scanning comparison section, data of the position and the length of a partial data string on the data of the immediately preceding line stored in the dictionary buffer is outputted as data of that partial data string of the current line.
