Abstract: THE IMAGE DECODING METHOD INCLUDES: DETERMINING A CONTEXT FOR USE IN A CURRENT BLOCK, FROM AMONG A PLURALITY OF CONTEXTS (S204); AND PERFORMING ARITHMETIC DECODING ON A BIT SEQUENCE CORRESPONDING TO THE CURRENT BLOCK, USING THE DETERMINED CONTEXT (S210), WHEREIN IN THE DETERMINING (S204): THE CONTEXT IS DETERMINED UNDER A CONDITION THAT CONTROL PARAMETERS (130, 230) 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 (S206); AND THE CONTEXT IS DETERMINED UNDER A CONDITION THAT THE CONTROL PARAMETER (130, 230) OF THE UPPER BLOCK IS NOT USED, WHEN THE SIGNAL TYPE IS A SECOND TYPE (S207), AND THE SECOND TYPE IS “NO_RESIDUAL_DATA_FLAG”.

Abstract: An image coding method includes: performing context arithmetic coding (SS11) to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding (SS12) to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.

Abstract: The image decoding method includes determining a context for use in a current block, from among a plurality of contexts (S204), wherein in the determining (S204): 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 (S207), 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".

Abstract: THE IMAGE DECODING METHOD INCLUDES: DETERMINING A CONTEXT FOR USE IN A CURRENT BLOCK TO BE PROCESSED, FROM AMONG A PLURALITY OF CONTEXTS (S204); AND PERFORMING ARITHMETIC DECODING ON A BIT SEQUENCE CORRESPONDING TO THE CURRENT BLOCK, USING THE DETERMINED CONTEXT (S210), WHEREIN IN THE DETERMINING (S204): 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 (S206); 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 (S207).
