ABSTRACT:
A decoder receives a series of input words defining variable length facsimile codes and generates pixel data to form a facsimile of an image. A code windowing apparatus selects a variable length code from the received series of words. A decoding ROM generates intermediate codes and code window control signals in response to the selected variable length codes. A reference windowing apparatus connected to receive pixel data generated during the decode of a previous scan line of the facsimile, selects a reference window of pixel data from a previous scan line. A color change detector indentifies a position of a color change picture element in the reference window. Output pixel data is generated in response to the intermediate codes and the position of the color change picture element in the reference window.
