    Abstract: Systems and methods for reducing chrominance (chroma) noise in image data are provided. In one example of such a method, image data in YCC format may be received into logic of an image signal processor. Using the logic, noise may be filtered from a first chrominance component or a second chrominance component, or both, of the image data, using a sparse filter and a noise threshold. The noise threshold may be determined based at least in part on two of the components of the YCC image data.

    Abstract translation: 提供了降低图像数据中色度(色度)噪声的系统和方法。 在这种方法的一个示例中,YCC格式的图像数据可以被接收到图像信号处理器的逻辑中。 使用该逻辑,可以使用稀疏滤波器和噪声阈值从图像数据的第一色度分量或第二​​色度分量或两者中滤除噪声。 噪声阈值可以至少部分地基于YCC图像数据的两个分量来确定。
