    • An image decoding device is provided which includes an intra prediction module for reconstructing an intra prediction mode and creating a prediction block of a current block or a sub block, an inverse scanning module for converting residual signals into a quantization block, an inverse quantization module for inversely quantizing the quantization block, and an inverse transform module for inversely-transforming the inversely-quantized block. A quantization parameter predictor for deriving the quantization parameter is created using quantization parameters of a left coding unit and a top coding unit of a current coding unit. Therefore, it is possible to improve image quality by adaptively adjusting a quantization parameter of a current block depending on the size of a coding unit and enhance compression efficiency of an image by effectively encoding/decoding the quantization parameter to reduce the number of bits required for transmitting the quantization parameter.
    • 提供一种图像解码装置,其包括:帧内预测模块,用于重构帧内预测模式并创建当前块或子块的预测块;反相扫描模块,用于将残差信号转换为量化块;逆量化模块, 对量化块进行逆量化,以及用于逆变换逆量化块的逆变换模块。 使用当前编码单元的左编码单元和顶编码单元的量化参数来创建用于导出量化参数的量化参数预测器。 因此,可以通过根据编码单元的尺寸自适应地调整当前块的量化参数来提高图像质量,并通过有效地对量化参数进行编码/解码来提高图像的压缩效率,从而减少对于 发送量化参数。
