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