FIELD: encoding/decoding images.
SUBSTANCE: invention helps determining whether or not bi-directional optical flow (BDOF) or prediction granularity with optical flow (PROF) is applied to the current block, based on the BDOF or PROF applied to the current block, sampling the current block prediction sample from the current block reference frame based on motion information of the current block and extracting a detailed prediction sample of the current block by applying BDOF or PROF to the current block based on the sampled prediction sample.
EFFECT: provision of efficient encoding and decoding.
