<p>A method and apparatus for data compression in a digital imaging process is disclosed. More specifically, a method is disclosed whereby a more efficient reduction of memory space is obtained when a dithered image is of the so called "grey scale" type. The binary bits representing the pixels of the dithered image are differentiated to obtain groups of ones or zeros, so that these groups may be represented by a code, thereby saving memory space. One embodiment uses the Exclusive OR function in the differentiation process.</p> |
