ABSTRACT:
A high speed facsimile device suitable for integration using present day VLSI technology, for encoding binarily digitized picture information into run length codes. The device receives consecutive blocks of digitized picture data. In the device a run length generator unit, which is responsive to these consecutive blocks of picture data, generates the run lengths of color units in a data block. A combining unit coupled to the run length generator unit combines the run lengths of color units in more than one data block and an encoding unit coupled to the run length generator block and the combining unit generates in a pre-determined code, such as the recommended CCITT T.4 standard, the coded run lengths of color units independent of the data blocks.
