1. An image decoding method performed by a decoding apparatus, comprising:
determining whether to perform filtering on signals to be used for generating intra prediction signals of decoding target signals, the signals being reconstructed earlier than the decoding target signals, the signals being adjacent to the decoding target signals;
performing the filtering on the signals when the filtering is determined to be performed;
generating the intra prediction signals of the decoding target signals based on the filtered signals; and
reconstructing the decoding target signals based on the intra prediction signals,
wherein whether to perform the filtering is determined based on a block size and an intra prediction mode of the decoding target signals,
wherein a tap size of a filter used for the filtering or a coefficient of the filter is variably determined based on a strength of the filter, and
wherein available tap sizes for the filter comprise 2-tap and 3-tap.
