Claim 1:
2. An encoding method, comprising:
determining whether or not a ternary split process of splitting a block into three sub blocks in a first direction parallel to a first longer side of the block is allowed by comparing a size of a second shorter side of the block to a minimum threshold value;
responsive to the ternary split process being allowed, writing, into a bitstream, a split direction parameter indicative of a splitting direction;
splitting the block into a plurality of sub blocks in a direction indicated by the split direction parameter;
splitting the block into a plurality of sub blocks in a second direction parallel to the second shorter side of the block when the ternary split process is not allowed; and
encoding the plurality of sub blocks.
