Abstract
A video decoding method includes, determining a center motion vector of a current block by using a base motion vector of the current block based on affine model-based inter-prediction being performed in the current block, determining a reference range of an area to be referred to, with respect to the current block, based on a size of the current block, based on a reference area having a size of the reference range with respect to a point in a reference picture of the current block, the point being indicated by a central motion vector of the current block, deviating from or including a boundary of the reference picture, changing the reference area by parallelly translating the reference area into a current picture, and determining prediction samples of sub-blocks of the current block in the changed reference area from the reference picture.
