摘要 |
<p>The image decoding method of an embodiment of the present invention includes: a context control step (S204) for determining the context to be used for a block to be processed, among a plurality of contexts; and an arithmetic decoding step (S210) for using the determined context to arithmetically decode a bit sequence corresponding to the block to be processed. In the context control step (S204), if a signal type for control parameters is a first type, the context is determined by using a condition that utilizes control parameters for both a left block and an above block, which are adjacent to the block to be processed (S206), and if the signal type for the control parameters is a second type, the context is determined by using a condition that does not utilize the control parameter for the above block (S207).</p> |
