Hauptman Ham, LLP
Method and apparatus for image encoding/decoding
A video decoding apparatus using an intra prediction, includes: a decoder to obtain mode information of a current block and residual sub-blocks corresponding to a plurality of sub-blocks included in the current block, from a bitstream; an intra predictor to select an intra prediction mode of the current block from among a plurality of intra prediction modes, based on the obtained mode information, identify the plurality of sub-blocks of the current block, and sequentially predict the plurality of sub-blocks by using neighboring pixels adjacent to each of the plurality of sub-blocks; an inverse quantization and transform unit configured to inversely quantize and then inversely transform each of the residual subblocks; and an adder configured to sequentially reconstruct the plurality of sub-blocks by adding each of the predicted sub-blocks to an inversely quantized and inversely transformed residual sub-block corresponding thereto.
