Abstract
An arithmetic decoding device includes a calculating unit that calculates candidates for split information using probability information, the split information indicating a boundary between a first value range and a second value range in range information, the probability information indicating whether a next item of binary data takes the first or second value, and the range information indicating a possible range of positional information obtained from a stream; a selecting unit that selects the split information corresponding to the range information from among the candidates; and a generating unit that generates the binary data according to which range of the range information divided at the split information includes the positional information and generates a next piece of the range information and a next piece of the positional information using the generated binary data. A process of the calculating unit and that of the generating unit are pipelined.
