摘要

A video encoding/decoding device according to the present invention may determine an intra prediction mode of a current block on the basis of a most probable mode (MPM) of the current block or an intra prediction mode of a neighboring block, determine a reference region for intra prediction of the current block, and perform intra prediction on the current block by using the intra prediction mode and the reference region.

說明書

(2) When Both intraPredModeL and intraPredModeA are Directional Modes, intraPredModeL is Greater than intraPredModeA and a Difference Between intraPredModeL and intraPredModeA is 1 or 64

The MPM of a current block may include intraPredModeL, intraPredModeA, and a default mode. The MPM of a current block may additionally include at least one of a mode derived by subtracting 1 from intraPredModeL, a mode derived by adding 1 to intraPredModeL, a mode derived by subtracting 2 from intraPredModeL or a mode derived by adding 2 to intraPredModeL. When the mode derived by subtracting or adding 1 from or to intraPredModeL is the same as intraPredModeA, it may be excluded from a MPM. In this case, the mode derived by subtracting or adding 2 from or to intraPredModeL may be added/included as a MPM.

An index may be assigned to the MPM based on a predetermined priority. For example, an index may be assigned to each MPM as in the following Table 3. But, a priority of the present disclosure is not limited to Table 3 and a position of a MPM in a candidate mode list may be different from Table 3.

TABLE 3 mpm[0] intraPredModeL mpm[1] intraPredModeA mpm[2] PLANAR mpm[3] DC
