摘要： A method and device for decoding two-dimensionally encoded digital facsimile signals. The method includes (a) accumulating the run lengths of color change picture elements in the reference line, (b) decoding a codeword to generate a displacement value, (c) combining the accumulated run length of a reference line color change picture element and a displacement value to obtain accumulated run lengths of coded line color change picture elements, and (d) determining the difference between accumulated run lengths of a coded line color change picture element. The difference is the decoded data. The device has a control logic, a reference line processor for generating the accumulated run lengths of color change picture elements in the reference line, a coded line processor for generating displacement values from the encoded codewords, and a combining part for combining the reference line accumulated run lengths and the displacement values to obtain the accumulated run lengths of color change picture elements in the coded line and for determining the differences between coded line accumulated run lengths, which are the decoded run lengths of the color units in the coded line.

摘要： 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.

摘要： A high speed picture element generator for use in a digital facsimile receiver for reforming picture elements from decoded facsimile transmission signals. The picture element generator receives the decoded facsimile signals in the form of run length data of sequential color units in a line of picture. An input register of the picture element generator receives the run length data of a color unit, and an output register holds the picture element data. A decoder, coupled to the input register, generates the picture element data for the output register from the run length data. The decoder is also coupled to the output register so that the generated picture data fills portions of the output register unoccupied by the picture element data of previous color units.

摘要： A method and device for two-dimensionally coding digital facsimile signals, especially for the CCITT T.4 recommended standard. A line of digitized picture elements is coded with respect to a reference line of digitized picture elements. The run lengths of color units previous to color change picture elements in the coding and reference lines are accumulated, and the positions of the color change picture elements in the coding line with respect to the positions of the color change picture elements in the reference line are determined by the differences between the accumulated run lengths of the coding and reference line color change picture element and the reference line color change picture elements. The steps are selectively repeated in predetermined sequences responsive to the value of the accumulated run length differences. The present invention also provides for a facsimile device which has control logic for controlling the operations of the device, sequential generators of the accumulated run lengths of each change picture element in the coding line and reference line, logic for determining the differences in the accumulated run lengths of coding and reference line picture elements and an encoder for encoding the difference in accordance with a predetermined code, whereby the control logic responsive to the differences, selectively advances the generators for the accumulated run lengths of the next coding line and reference line change picture elements.
