Abstract:
The image coding method includes: determining a context for a current block to be processed, 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 one of “mvd_l0” and “mvd_l1”.

Claim (Index 2):
A coding apparatus for coding a control parameter for controlling coding of an image, the coding apparatus comprising:\n a context determination unit configured to determine a context for a current block in the image, from among a plurality of contexts; and an arithmetic coding unit configured to perform arithmetic coding on the control parameter for the current block to generate a bitstream corresponding to the current block, wherein the context determination unit is configured to: determine a signal type under which the control parameter for the current block is classified; determine the context by using both of coded control parameters for a left block and an upper block, when the signal type is a first type, the left block being a neighboring block to the left of the current block, and the upper block being a neighboring block on top of the current block; and determine the context by using a predetermined fixed value, without using any of the coded control parameters for the left block and the upper block, when both coded control parameters of the left block and the upper block are not available or when the signal type is a second type different from the first type, wherein the context determination unit is configured to determine whether or not the coded control parameter of the upper block is available, according to a hierarchical depth of a data unit to which the control parameter of the current block belongs, wherein the control parameter determined as the first type belongs to the current block having a size larger than or equal to a size of a block to which the control parameter determined as the second type belongs, wherein one of a split flag and a skip flag is classified under the first type, the split flag indicating whether or not the current block is partitioned into a plurality of blocks, and the skip flag indicating whether or not the current block is to be skipped, and wherein a difference parameter is classified under the second type, the difference parameter indicating a difference between a motion vector and a motion vector predictor of the current block.
