Abstract
An image decoding/encoding method and device disclosed herein may: determine a co-located block for temporal motion vector prediction of the current block; derive a block vector from the co-located block; derive a motion vector of the current block on the basis of the block vector; and generate a prediction signal of the current block by performing inter-prediction on the basis of the motion vector of the current block.
