1. An image decoding method performed by an image decoding apparatus, the image decoding method comprising:
selecting an arithmetic decoding process corresponding to a symbol segment; and
decoding at least one symbol included in the symbol segment in response to the arithmetic decoding process,
wherein the arithmetic decoding process is selected based on a number of symbols included in the symbol segment.
