ABSTRACT:
An image encoding device for effecting the carryover process on a real-time basis in arithmetic encoding, and without interruption in the function of the arithmetic encoder. The device is provided with an encoder for outputting code data, encoded by arithmetic codes, in succession by a predetermined number of bits, shift registers for retaining plural sets of the code data output from the encoder, and a processor for applying a carry-over process to the thus retained plural sets of code data.
