A PVC method using visual recognition characteristics includes generating a residual signal between an input block, which is included in at least one frame, and prediction data generated from an inter-frame prediction or intra-frame prediction. The PVC method further includes calculating a transform domain JND for the input block; shifting the calculated JND based on the size of the input block; and subtracting the shifted transform domain JND from a transform coefficient of the residual signal and quantizing the same.
