Title:
IMAGE ENCODING METHOD, IMAGE ENCODING DEVICE, IMAGE DECODING METHOD, IMAGE DECODING DEVICE, AND IMAGE ENCODING/DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/051209
Kind Code:
A1
Abstract:
An image encoding method comprises: a step for dividing a block to be encoded into a plurality of sub-blocks; a step for obtaining, for each of the sub-blocks, merge candidates that are candidates for a set consisting of a prediction direction, a motion vector, and a reference picture index; a step for selecting a merge candidate; and a step for adding an index for specifying the selected merge candidate to a bit stream. Executed in the step for obtaining the merge candidates are: first evaluation processing that evaluates, for each of the blocks adjacent to the sub-blocks, whether the adjacent block is included in the block to be encoded, and determines an adjacent block not included in the block to be encoded as a block to be merged; and first derivation processing that derives a first candidate as one of the merge candidates, using the aforementioned set which was used in generating a prediction image for the block to be merged.
