摘要 |
An image decoding method according to one embodiment of the present invention comprises: a context control step (S204) in which a context to be used for a block to be processed is determined from a plurality of contexts; and an arithmetic decoding step (S210) in which the determined context is used to arithmetically decode a bit string corresponding to the block to be processed. In the context control step (S204), if the signal classification of a control parameter is a first type, the context is selected using a condition whereby the control parameters of the left-side adjacent block and upper adjacent block of the block to be processed are employed (S206), and if the signal classification of the control parameter is a second type, the context is determined using a condition whereby the control parameter of the upper block is not employed (S207). The second type is "no_residual_data_flag". |
