Abstract:
The amount of processing is reduced with high coding efficiency maintained. There is provided an arithmetic decoding device including syntax decoding means for decoding each of at least a first syntax element and a second syntax element indicating a transform coefficient using arithmetic decoding with a context or arithmetic decoding without a context. The syntax decoding means performs decoding that at least includes not decoding the first syntax element and decoding the second syntax element using the arithmetic decoding without a context, and decoding the first syntax element using the arithmetic decoding with a context and decoding the second syntax element using the arithmetic decoding without a context.

Claim (Index 3):
An encoding device for encoding data, the encoding device comprising:\n a coefficient presence/absence flag encoding circuitry that encodes a sub-block coefficient presence/absence flag indicating whether or not at least one of transform coefficients of the sub-block at position (x, y) has a non-zero value, wherein the coefficient presence/absence flag encoding circuitry encodes a coefficient presence/absence flag indicating whether a corresponding transform coefficient is equal to non-zero, if a value of the sub-block coefficient presence/absence flag is equal to one, if a value of the coefficient presence/absence flag is equal to one, the coefficient presence/absence flag encoding circuitry performs encoding function (i) or (ii):\n (i) encoding a coefficient absolute level greater one flag indicating whether an absolute value of the transform coefficient is larger than one, and encoding a coefficient absolute level remaining parameter indicating a remaining absolute value of the transform coefficient, and \n (ii) not encoding the coefficient absolute level greater one flag and encoding the coefficient absolute level remaining parameter, \n if the value of the coefficient presence/absence flag is equal to zero, the coefficient presence/absence flag encoding circuitry does not encode the coefficient absolute level greater one flag and the coefficient absolute level remaining parameter, and the coefficient presence/absence flag encoding circuitry encodes (i) the sub-block coefficient presence/absence flag using a context, (ii) the coefficient presence/absence flag using a context (iii) the coefficient absolute level greater one flag using a context, and (vi) the coefficient absolute level remaining parameter using a bypass mode.
