    • PURPOSE: A method for encoding and decoding in an intra prediction mode is provided to simply induce an intra prediction mode without a complicated operation process. CONSTITUTION: If two identical induced most probable modes (MPMs) induced in adjacent prediction units are not included in at least two set prediction modes, an image encoding device sets up remaining two MPMs of an MPM list consisting of three MPMs for a current prediction unit out of the set prediction mode and a proximity prediction mode adjacent to the induced MPMs (S1001,S1003). The image encoding device encodes a prediction mode for the current prediction unit based on the induced MPMs and the set remaining two MPMs. [Reference numerals] (AA) MPM list organization; (S1001) Left MPM=Previously-defined encoding mode A or Left MPM=Previously-defined encoding mode B; (S1002) MPM[0]=Previously-defined encoding mode A, MPM[1]=Previously-defined encoding mode B, MPM[2]=Previously-defined encoding mode C; (S1003) MPM[0]=Left MPM, MPM[1]=Previously-defined encoding mode A, MPM[2]=Previously-defined encoding mode B
    • 目的:提供一种帧内预测模式的编码和解码方法,以简单地引导帧内预测模式,而不需要复杂的操作过程。 构成:如果在至少两组预测模式中不包括在相邻预测单元中诱导的两个相同的诱导最可能模式(MPM),则图像编码装置设置由用于当前预测单元的三个MPM组成的MPM列表的剩余两个MPM (S1001,S1003)附近的邻近预测模式。 图像编码装置根据诱导的MPM和剩下的两个MPM对当前预测单元的预测模式进行编码。 (附图)(AA)MPM清单组织; (S1001)左MPM =以前定义的编码模式A或左MPM =以前定义的编码模式B; (S1002)MPM [0] =以前定义的编码模式A,MPM [1] =以前定义的编码模式B,MPM [2] =以前定义的编码模式C; (S1003)MPM [0] =左MPM,MPM [1] =以前定义的编码模式A,MPM [2] =以前定义的编码模式B

    • PURPOSE: A method for inducing a prediction MV(Motion Vector) and a device using the method are provided to reduce complexity generated when inducing the prediction MV by calculating a final prediction MV by forming a candidate prediction MV list. CONSTITUTION: An image encoding/decoding device induces temporal candidate prediction MV information based on spatial candidate prediction MV information(S1420). The device adds an induced candidate prediction MV to a candidate prediction MV list(S1430). The device removes the same candidate prediction MV to reform the candidate prediction MV list(S1440). The device determines a final prediction MV from the candidate prediction MV list(S1460).
