Image encoding/decoding method and device, and recording medium in which bitstream is stored

A method of encoding an image, the method comprising:

• generating prediction information and residual signal information for a current block;
• and
• reconstructing, based on the prediction information and the residual signal information, the current block,
• wherein the prediction information comprises at least one among a regular merge mode information, an MMVD (Merge mode with Motion Vector Difference) mode information, a triangular partition mode information, a CIIP (Combined Inter and Intra Prediction) mode information, an IBC (Intra Block Copy) mode information and a subblock merge mode information, and
• wherein the MMVD mode information is encoded based on the regular merge mode information.

A non-transitory computer-readable recording medium storing a bitstream decoded by an image decoding apparatus,

• wherein the bitstream includes prediction information and residual signal information for a current block,
• wherein the prediction information is used for judging a prediction mode of the current block,
• wherein the current block is reconstructed based on the prediction information and the residual signal information,
• wherein the prediction information is obtained through entropy decoding in the image decoding apparatus, and
• wherein a context model used for the entropy decoding of the prediction information is determined based on a prediction mode of a neighboring block of the current block.
