<p>PURPOSE:To provide a data compressing and expanding system capable of compressing/expanding the print image of a printer and facsimile equipment, etc., satisfactorily. CONSTITUTION:This system is constituted of an image data compression system (a) consisting of a first encoder part 103 by a universal code, a second encoder part 104 by the runlength of the same data, a counter part 101 which counts the continuance of the same data, a comparison part 102 which compares a count value counted by the counter part with a prescribed value, and an output part 105 which operates either the first encoder part or second encoder part according to the result of the comparison part and outputs by unifying encoded data by the first and second encoder parts, and an image data expanding system (b) to decode a compression signal by the image data compression system.</p> |
