Method of and apparatus for encoding, method of and apparatus for decoding, and image forming apparatus

摘要

With an encoding section 301 in an encoding apparatus, an image reading section 310 sequentially inputs binary signals by a predetermined bit length; a run counter in a run length processing section 320 outputs a run length determined within the binary signal of the predetermined bit length input by the image reading section 310 and a run length not determined within the binary signal; an adder in the run length processing section 320 adds the indeterminate run length to the first run length of a binary signal of the predetermined bit length to be subsequently input by the image reading section 310 , and encoding unit 340 encodes the run length output by the run length processing section 320.
