Embodiment Construction
[0042] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.
[0043] Figure 4 is a flowchart illustrating an encoding method based on intra prediction according to an exemplary embodiment of the present invention. refer to Figure 4 , in operation 410, an intra prediction encoding device ("encoding device") according to an exemplary embodiment of the present invention performs intra prediction on a current block and determines an intra prediction direction of the current block. As described above, the optimal direction is determined in consideration of the residual and distortion between the original block and the predicted block, and is determined as the intra prediction direction.
[0044] After the intra-frame prediction direction is determined, intra-frame prediction encoding is performed according to the determined direction. Such as figure 1 and figure 2 As sh...
