Claim 2:
3. An image encoding method comprising:
when a split shape mode of a current coding unit is determined as a horizontal binary-split, determining two lower coding units by splitting a height of the current coding unit in half;
when the split shape mode of the current coding unit is determined as a vertical binary-split, determining the two lower coding units by splitting a width of the current coding unit in half;
when the split shape mode of the current coding unit is determined as a horizontal tri-split, determining three lower coding units by splitting the height of the current coding unit by a ratio of 1:2:1;
when the split shape mode of the current coding unit is determined as a vertical tri-split, determining the three lower coding units by splitting the width of the current coding unit by the ratio of 1:2:1;
when the split shape mode of the current coding unit is determined as a no-split, decoding the current coding unit;
determining a context model based on at least one of a width or a height of a neighboring coding unit of the current coding unit and at least one of the width or the height of the current coding unit; and
encoding information about the split shape mode of the current coding unit into a bitstream by performing entropy coding based on the context model,
wherein the neighboring coding unit includes a neighboring coding unit adjacent to the right of the current coding unit,
wherein the neighboring coding unit is encoded before the current coding unit.
