Abstract: PURPOSE: An image encoding method using a prediction mode and a computer-readable medium thereof are provided to encode each sub block by referring to a pixel of an adjacent block by encoding a sub block including a reference pixel earlier than a corresponding sub block. CONSTITUTION: When an encoder applies a diagonal down-left direction to a prediction mode, the encoder determines pixels in E,F,G,H as reference pixels to encode a sub block. The encoder determines a pixel of the sub block as a reference pixel to encode a sub block on the left bottom. When the diagonal down-left direction is determined as a prediction direction, the encoder determines an encoding sequence in order of an upper right end (430), an upper left end (440), a lower right end (450), and a lower left end (460).

Abstract: PURPOSE: A de-blocking method for a prediction block and a device thereof are provided to increase the efficiency of an encoding or decoding process by determining a boundary filtering strength when a skip encoding mode is applied to a boundary block. CONSTITUTION: When one or more encoded blocks exist in a block p and a block q, a de-blocking device determines a boundary filtering strength as 0 (S800, S810).
