1. An image decoding method comprising:
obtaining, from a bitstream, first information indicating a motion vector resolution of a current unit among a plurality of motion vector resolutions including a first motion vector resolution and a second motion vector resolution;
obtaining, from the bitstream, second information indicating whether a merge mode is applied to the current unit or not when the first information indicates the first motion vector resolution; and
decoding the current unit based on the merge mode when the second information indicates that the merge mode is applied to the current unit,
wherein when the first information indicates the second motion vector resolution, the second information is not obtained from the bitstream, and
wherein, in the merge mode, the current unit is decoded using a motion vector of the current unit, the motion vector of the current unit being determined using a motion vector of a neighboring unit.
