Abstract:
The image coding method includes: determining a context in a current block in the image, from among a plurality of contexts; and performing arithmetic coding on the control parameter for the current block to generate a bitstream corresponding to the current block, wherein in the determining: the context is determined under a condition that control parameters of neighboring blocks of the current block are used, when the signal type is a first type, the neighboring blocks being a left block and an upper block of the current block; and the context is determined under a condition that the control parameter of the upper block is not used, when the signal type is a second type, and the second type is (i) “merge_flag”, (ii) “ref_idx_l0” or “ref_idx_l1”, (iii) “inter_pred_flag”, (iv) “mvd_l0” or “mvd_l1”, (v) “no_residual_data_flag”, (vi) “intra_chroma_pred_mode”, (vii) “cbf_luma”, and (viii) “cbf_cb” or “cbf_cr”.

Claim (Index 2):
The decoding method according to  claim 1 , further comprising:\n switching between decoding processes based on a codec standard in accordance with which coding has been performed to obtain the image, wherein in the determining of a context, the context for the control parameter classified under the second type is also determined by using both of the decoded control parameters for the left block and the upper block, when the codec standard is a first standard, and the context for the control parameter classified under the second type is determined by using the predetermined fixed value, without using any of the decoded control parameters for the left block and the upper block, when the codec standard is a second standard.
