    • PURPOSE: An image coding/decoding method and device are provided to reduce hardware complexity and operation power consumption of an image coding device and/or an image decoding device. CONSTITUTION: An image decoding device obtains a differential block for a chroma component of a decoding object block and a parameter for decoding of the decoding object block(S810). The image decoding device determines whether or not a boundary of the decoding object block corresponds to a boundary of an LCU(Largest Coding Unit)(S820). The image decoding device generates a prediction block for the chroma component based on a parameter(S830). The image decoding device generates a reconstruction block by adding the differential block to the prediction block(S840). [Reference numerals] (AA) Start; (BB) End; (S810) Obtain a differential block and a parameter; (S820) Determine whether or not a boundary of a current block corresponds to a boundary of an LCU; (S830) Generate a prediction block; (S840) Generate a reconstruction block
    • 目的:提供图像编码/解码方法和装置,以降低图像编码装置和/或图像解码装置的硬件复杂度和操作功耗。 构成:图像解码装置获得解码对象块的色度分量的差分块和解码对象块的解码用参数(S810)。 图像解码装置判定解码对象块的边界是否对应于LCU(最大编码单位)的边界(S820)。 图像解码装置基于参数生成色度分量的预测块(S830)。 图像解码装置通过将差分块加到预测块来生成重构块(S840)。 (附图标记)(AA)开始; (BB)结束; (S810)获取差分块和参数; (S820)确定当前块的边界是否对应于LCU的边界; (S830)生成预测块; (S840)生成重建块
