色度补偿方法和装置
摘要：
本发明实施例涉及一种色度补偿方法，包括：将原始参考帧的亮度分量和两个色度分量，进行加权预测处理；生成加权参考帧的亮度分量和两个色度分量的值。本发明实施例还涉及一种色度补偿装置，包括：处理模块，用于将原始参考帧的亮度分量和两个色度分量，进行加权预测处理；生成模块，用于生成加权参考帧的亮度分量和两个色度分量的值。本发明实施例还涉及一种色度补偿装置，包括：第一补偿模块，用于对亮度值Y进行加权补偿；第二补偿模块，用于对第一色度值U进行加权补偿；第三补偿模块，用于对第二色度值V进行加权补偿；加法器。因此，本发明实施例色度补偿方法和装置实现了利用加权预测对视图间参考帧存在颜色不匹配进行色度补偿，降低码率。
摘要（英）：

The inventive embodiment relates to a chrominance compensation process, including: performing weighting forecast processing to luminance component and two chrominance components of the original reference frame; and generating the values of the luminance component and two chrominance components of the weighting reference frame. The inventive embodiment also relates to a chrominance compensation device, including: a processing module, for performing weighting forecast processing to luminance component and two chrominance components of the original reference frame; and a generating module, for generating the values of the luminance component and two chrominance components of the weighting reference frame. The inventive embodiment also relates to a chrominance compensation device, including: a first compensation module, for performing weighting compensation to a luminance value Y; a second compensation module, for performing weighting compensation to a first chromatic value U; a third compensation, for performing weighting compensation to a second chrominance value V; and an adder. Therefore, the chrominance compensation process and device of the inventive embodiment uses weighting forecast to perform chrominance compensation to color mismatch existing between reference frames of views to reduce code rate.
